CenturyLink offers excellent fiber internet, but it’s available only in limited markets. If you can't get fiber, you may be able to get a DSL connection but you'll pay nearly as much.
Sparklight, formerly known as Cable One, is a cable internet provider primarily serving suburbs and rural areas in over a dozen states. Its no-contract plans offer good download speeds to areas fiber doesn’t often reach, but its data caps aren’t ideal.
Xfinity is a fantastic provider overall. It offers fast speeds, reliable service, and reasonable prices. Some plans still require contracts, and others still have data limits. Watch out for Xfinity’s hidden fees and spotty customer service record, but it may not be as bad as it once was.
CenturyLink offers two types of plans, depending on your location. The more common option is DSL, which is relatively slow and offers inconsistent speeds. The other option is fiber, which is extremely fast and reliable.
Generally speaking, the DSL options are not a great value. The price is reasonable, but the speeds mean you’re likely to get more for your money elsewhere (this is true for many DSL providers). The fiber plans are a much better value—they offer much more speed for the money than CenturyLink’s DSL plans and are competitive with other providers’ fiber offerings. In fact, CenturyLink's 940 Mbps plan costs a little more than half of the national benchmark for similar plans. (1) We highly recommend CenturyLink fiber if you have it available.
Sparklight’s no-contract cable internet plans are generally a decent value compared to other providers available in the communities the company serves. While you might not be able to get fiber in these areas, you’re likely to find DSL, satellite, or other cable internet service providers (ISPs). The speed you get for the price is comparable to other cable providers or a bit cheaper, and the performance surpasses DSL and satellite. All of this means Sparklight’s plans are worth strongly considering if your address is in one of its service areas.
We recommend choosing a Sparklight plan with at least 200 Mbps of download speed, but ideally more if it’s in your budget. Since Sparklight is a cable provider, upload speeds tend to be far below the download speeds. Upload speeds increase with each pricing tier, so if you work from home and have multiple connected devices you may want to pick one of the more expensive plans for seamless video calls.
All of Sparklight’s plans have data caps, except for its most expensive Gig plan. Data caps are typical for cable providers. While some competitors offer data caps over 1 TB for all of their plans, Sparklight’s plans have data caps that range from 100 GB to 1.5 TB. You can get 100 GB blocks of additional data for $10 during months when you need it, or you can upgrade to unlimited data with any plan for an extra $30/month. When calculating your needs, consider that the average person uses 536 GB of data per month (1).
The Gig plan offers the most data for your dollar and the highest speeds, but it’s more expensive than fiber plans with comparable download speeds, at least in some of the service areas. If you don’t want to pay top dollar, the Internet 300 and 500 plans also offer good speeds and high enough data caps for the needs of most households. We wouldn’t recommend the Internet 25 plan because its low speeds and data cap won’t comfortably meet most people’s needs.
Xfinity is generally a very good value, especially at the middle and lower tiers. In fact, it offers some of the best budget plans of any of the major internet service providers. Eligible households may qualify for high-speed internet as low as $9.95 a month with unlimited data and equipment.
Depending on your area, you can get a 50 Mbps Internet Essentials plan for less than $20 per month and a 400 Mbps plan for $50 per month. Those plans have a data cap of 1.2 terabytes which is a high data cap. Data caps are common among cable internet service providers (ISPs). Removing it costs an extra $30. But overall, this pricing is an excellent deal for the speeds you're getting.
The 400 Mbps plan, which is about right for an average family that's online a lot, is also a great price. It rings in at about 36% of the national benchmark in its range. (1) That means you're paying just $0.18 per megabit, with plenty of megabits to go around.
Faster internet plans are available from Xfinity. Some areas can get speeds up to 2 Gbps, and others can get plans as fast as 6 Gbps. For reference, 6 Mbps is ridiculously fast, and it also comes at a higher price. Most households don’t need 6 Gbps internet speeds unless they’re streaming a ton of 4K content or have several people gaming online at the same time. These fast internet plans do come with unlimited data, though, so it might still be worth it for some households.
There’s a performance divide based on the type of service available. The CenturyLink DSL plans can range from 15 to 100 Mbps, which is a wide range. Additionally, 15 Mbps just isn’t great these days. It doesn’t even reach broadband speeds (25 Mbps or more). That said, you shouldn’t have to worry about getting the advertised speed—whatever plan you sign up for, you seem to get what you pay for with CenturyLink.
On the other hand, the fiber plans offer Gigabit speeds (up to 940 Mbps), which is excellent. Additionally, fiber internet offers synchronous download speeds and upload speeds, meaning you can game, video chat, or upload large files just as fast as you binge Netflix. Fiber also tends to be inherently reliable because of the way the technology works—the light signals in fiber optic cables can carry more information over longer distances than coaxial cables. We have no complaints about performance on these plans.
Sparklight is available in mostly rural and suburban areas where customers probably won’t be able to get fiber internet. This makes Sparklight’s cable internet speeds the best option in some communities that are otherwise served only by DSL or satellite, which can be slow and unreliable. According to a report from Ookla, Sparklight had the highest download speeds among fixed broadband providers in North Dakota and New Mexico. (2)
Sparklight is a fiber-rich cable provider, meaning it delivers service using a mix of fiber and coaxial cables. While it can achieve download speeds of up to 940 Mbps, its upload speeds are much lower than that, reaching 50 Mbps. This is a technical limitation of cable connections that those with fiber connections won’t experience. While this isn’t ideal for households with several people who want to do heavy gaming or take video calls at the same time, Sparklight’s download and upload speeds are generally still sufficient for most households. And for regular browsing and streaming for multiple users, it's just fine. However, the data caps may hold you back if you’re a heavy internet user. Occasional outages and inconsistent speeds do affect service according to customer reports on Downdetector. (3)
Xfinity internet performance is excellent. Its speeds are fast and reliable. In fact, in many markets, it has one of the fastest internet speeds around. Xfinity's internet service is reliable and consistent. If outages occur, Xfinity is responsive and generally restores service within hours. Xfinity internet is also highly rated for speed (2), and research from the US Federal Communication Commission (FCC) scored it among the top for reliability (3).
CenturyLink installation is more or less on par with other providers in terms of installation procedures and costs. If your neighborhood is wired for only DSL with CenturyLink, you can have your internet service set up by a pro for somewhere between $129 and $300 based on the installation requirements. You can alternatively choose to do a self-install for $15.
If you live in an area wired for CenturyLink fiber, your pro installation and equipment rental are free, and you may be able to self-install for free. You could also wrangle unlimited data and an included mesh wireless network if you sign a contract, so be sure to ask. This is about on par with other fiber internet providers.
Find out whether you need a professional to come by or if you can handle setup yourself.
As for equipment, the CenturyLink modem and router are also pretty standard stuff. The company charges around $15 per month for equipment rentals for DSL customers. The gear is nothing to write home about, but it works. You can also buy the modem outright from CenturyLink for up to $200—whether this is a good deal for you depends on how long you plan to have CenturyLink as a provider.
We don’t particularly recommend buying your own router. Both the DSL and fiber services require a modem certified by CenturyLink to function, so you may as well save some money and use the built-in wireless router.
When you sign up for Sparklight internet service, you can call to schedule professional installation or choose self-installation. Both options are reasonably fast according to customer reviews. Professional installation is typically free and can be scheduled at your convenience. There's technically a $90 professional installation fee, but it is waived as part of a "permanent promotion." Self-installation is free and should take about 15 minutes once you receive your equipment in the mail.
You can choose to purchase your own Sparklight-supported modem or lease a modem from Sparklight for just over $10/month, less than some other providers. The installation cost, activation fee, and any equipment deposits may be waived for qualifying new customers.
Xfinity internet offers the choice of professional and self-installation. The professional option is often more affordable than competitors, at $100. It's required if you haven't had Xfinity service at the address for more than 12 months. The self-install kit is free, but you may pay for shipping and handling. If you have trouble installing yourself, you can contact customer service for help, but beware that you may face long hold times.
As for equipment, the Xfinity xFi gateway is fairly typical (and costs a fairly typical $14 per month). You can add a Wi-Fi extender (and unlimited data) if you bump up to xFi Complete for about $15 per month for the first two years (and $25 per month starting in year 3). This is a bit steep for just the extender—you can grab an excellent Wi-Fi extender for right around $50. However, using Xfinity's equipment gives you unlimited data, and you qualify for a free upgrade after three years.

If you use your own equipment, unlimited data costs an extra $30 per month for lower tier plans, but is included for plans of at least 1 Gbps.
CenturyLink consistently scores slightly below average in customer satisfaction (2), largely due to complaints about a lack of responsiveness regarding customer service. The service also gets a lot of complaints from new fiber internet customers, but complaints are very common industry-wide.
CenturyLink hires techs and contractors from around the country, so some inconsistency is expected. It redeems itself slightly, though, with an easy-to-use support page.
The company is expanding and we hear that many new cities will have fiber internet hookups from CenturyLink within the next few years. If you can get only DSL, though, you may have a connection as slow as 3 Mbps or one as fast as 100 Mbps, with huge variation in latency depending on how far you are from the nearest access point.
We like that CenturyLink provides DSL to customers who may have no other option, but we don't recommend the DSL offering if you have access to cable or fiber internet from another provider.
Customer experience with Sparklight is about average compared to other providers. Tech support is available 24/7 by phone or email, and there are plenty of help articles available online. Like most other providers, equipment installation is straightforward whether you have it done professionally or do it yourself.
Common complaints include unplanned outages, inconsistent speeds, and long wait times to reach Sparklight support by phone, according to user reports on Downdetector. (4) If you try Sparklight’s internet service and it doesn’t live up to expectations, the company offers a 30-day money-back guarantee.
The Xfinity internet customer experience is a mixed bag. On the one hand, you have reliable service, with the option for unlimited data if you want it. This makes for a great day-to-day experience with Xfinity.
On the other hand, Xfinity internet has a spotty customer service track record. It ranks above average on customer surveys (4). While customer service seems to be above average, not everyone has a great experience, and we've seen some complaints about billing issues and miscommunication between the company and their technicians.
If you need to connect with the company, we recommend using its customer service portal and downloading the Xfinity app first before trying to reach reps by phone.
