Compare Xfinity vs. CenturyLink

Is Comcast’s Xfinity or CenturyLink better?

Is CenturyLink better than Xfinity? The answer is a pretty easy one for most people. If CenturyLink’s fiber internet service is available at your address, you should get it. But if all you can get is DSL from CenturyLink — any of its plans below 940 Mbps — Xfinity is a better choice. The cable internet that Xfinity uses is a much faster and more reliable option than DSL, but it’s not quite as strong as fiber. 

Quick comparison

• Fastest speeds: In most areas, Xfinity has much better speeds than CenturyLink. Both providers both offer gig speeds (940 Mbps), but Xfinity has it in more areas. In many places, all CenturyLink offers is slower DSL service.
• Most affordable: CenturyLink’s internet plans don’t increase in price after a year, and you’ll pay a flat $49/mo. for all of its DSL plans. In most areas, Xfinity internet prices increase significantly after 12 months.
• Contracts and hidden fees: Neither provider locks you into a contract, but Xfinity has no installation fee and its equipment rental is slightly cheaper. 
• Best in customer service: Xfinity scored higher in customer satisfaction for internet service in 2021 with a 67/100 compared to CenturyLink’s 62, according to the American Customer Satisfaction Index.

How we scored internet providers

We evaluate broadband providers in four categories: affordability, performance, value and customer satisfaction. Each category contains multiple sub-factors, all of which are weighted differently to impact the provider’s overall score. For each sub-factor, we score all providers on a continuous scale of 1 to 5, relative to the industry as a whole. Because the average download speed in America is currently 180 Mbps, for example, we assigned all plans with download speeds between 100 and 299 Mbps a score between 3 and 4. Xfinity’s 200 Mbps plan received a 3.50 score for download speed, while Spectrum’s 400 Mbps plan got a 4.16.

Which internet plan should you choose?

Equipment, installation, contracts and data caps

The sticker price isn’t the only thing you should pay attention to when comparing internet providers — there are often a number of extra fees that get added onto your bill. Here’s how CenturyLink and Xfinity compare when it comes to some of the extras:

• Equipment: CenturyLink charges $15/mo. for equipment rental, but it’s free on the Fiber Gigabit plan. Xfinity is slightly cheaper at $14/mo., but it doesn’t include it for free on any plans. For both providers, you also have the option of purchasing your own modem and router. 
• Installation: Xfinity doesn’t have any installation fees. CenturyLink charges $99, but it’s waived on some DSL and all fiber plans. 
• Contracts: Neither provider has contracts. You can cancel service any time without getting hit with early termination fees. 
• Data caps: CenturyLink has a 1TB (1,000GB) data cap on all of its DSL plans, while Xfinity’s are 1.23TB (1,229). Most people aren’t likely to come close to these, but if you live in a bigger household with heavy gamers or streamers, it’s worth considering. CenturyLink doesn’t charge you extra if you go over your cap, but it may throttle your speeds. Xfinity will give you one freebie month per year to go over, but after that, it’ll cost $10 for every 50GB you exceed the cap. 

CenturyLink vs. Xfinity internet and TV bundles

Xfinity offers savings for bundling internet with TV while CenturyLink does not. Xfinity bundles cable internet, TV and digital phone plans, while CenturyLink offers DSL or fiber optic internet and home phone services. If you’re looking for TV service with CenturyLink, you can get satellite through DIRECTV and DISH Network or streaming through DIRECTV STREAM, but they aren’t discounted. Overall, Xfinity gives customers more ability to mix and match internet speed options with TV channel plans than CenturyLink does.

Who is better for customer satisfaction? Xfinity vs. CenturyLink

Customers tend to be much more satisfied with their service from Xfinity than with CenturyLink. The American Customer Satisfaction Index (ACSI) scores internet providers based on feedback from customers and gives them an annual customer satisfaction score. Here’s how Xfinity and CenturyLink scored over the past four years.

Xfinity has outscored CenturyLink every year since 2016. J.D. Power also gave Xfinity a better score in every region where they overlapped internet service. Consumer Reports readers rated Xfinity higher, too, with better scores for both reliability and speed. This tracks with complaints about CenturyLink on Reddit and the Better Business Bureau: Its DSL plans are often slower than expected, and some customers have experienced frequent outages.
