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.
If you can get fiber internet from Optimum , you'll get great all-around service with fast speeds and reasonable pricing. If you can get only cable internet, you'll get slower max speeds and may see different pricing. Both options are decent, but watch out for third-year price hikes and potential customer service hassles.
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.
Optimum offers a lot for the money. Both fiber and cable internet plans start at 300–500 Mbps, with a very competitive price that beats the entry-level plan for competitor Spectrum and is way less than national benchmarks (1). That's plenty fast for most online gaming and work from home needs, but you can pay for even higher speeds if you have a big household.
Compared to the competition, the two lower-tier plans almost always offer more speed for the money. And while you can technically find cheaper gig plans, Optimum still tends to be the most affordable in its markets.
If you qualify only for cable internet with Optimum, your speeds will be slower but you'll pay about the same every month. Prices are higher than other cable internet providers at these speeds, but you may not have a choice. Most areas that don't have fiber internet won't have multiple cable internet options.
We love the low starting prices, 2-year price lock, and 60-day money back guarantee, but you can expect prices to jump $35–$85 in your third year of service.
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.
Optimum performance is solid. With speeds up to 2 Gbps (12000 Mbps) in some states, there’s enough bandwidth available for even the heaviest of streaming households. Even the lowest-tier plans offer plenty of speed for most use cases. The cable service is generally very reliable, as well, and usually even faster than advertised, with better latency than any cable competitor. (2)
Additionally, Optimum offers fiber internet service in some of its coverage areas, which offers extra reliability and symmetrical speeds. That’s an excellent feature for content creators and anyone who shares a lot of large media files. Recently, it started offering home internet plans up to 5 Gbps, a speed that’s nearly impossible to beat.
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.
Optimum offers a fairly standard wireless gateway with both its fiber and cable plans. The combined modem and router are usually free, but may cost you $10 per month on top of your bill in some areas. You can also add Wi-Fi extenders for $3 each per month, which is handy for larger homes and offices (and not a bad price, either).
If you want to use your own equipment instead of Optimum's free gear, you may run into difficulties. Optimum doesn't list compatible equipment and requires at least some third-party modems to be purchased from its stores.
With Optimum installation, you can do it yourself or have a pro help, and either way is free. If you order online, you can opt for a free standard professional installation or pay $59 for a premium installation, where the tech will configure Wi-Fi on up to six devices for you. While other providers may offer to set up your main device during installation, we haven’t seen such an extensive guarantee elsewhere. This could be a selling point for less tech-savvy 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.
Optimum provides a good customer experience overall. Both types—cable and fiber—are fast and stable, and we haven’t seen any major complaints about reliability. We think the day-to-day experience with Optimum is fine.
However, the company’s customer service is less than stellar, with one of the lowest ratings of all providers, according to the American Customer Satisfaction Index (ACSI) (3). Most of the complaints we’ve seen involve a poor experience dealing with customer service reps. Optimum does offer solid online support options, so you may be able to get around these issues. And, of course, not everyone has a poor experience.
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.
