CenturyLink vs Comcast Xfinity Internet

Jordan Grimmer
Jordan Grimmer | Senior Editor
CenturyLink and Xfinity have a lot in common as ISPs. As direct competitors in several areas, they have to consistently improve to at least match (if not exceed) the other provider's service. Because of this, the two share some similarities.

Comcast Xfinity and CenturyLink are prolific U.S. providers with a large coverage area. Xfinity covers 39 states and CenturyLink offers some coverage in all 50.

Both have some of the most affordable high speed plans in the industry, with fast download and upload speeds offered particularly in urban areas. Not every U.S. customer has access to multiple high speed service providers, so count yourself lucky that you have a choice between two of the best ranked.

Xfinity and CenturyLink both offer multiple connection types with some great bundling options. You have a range of broadband services available from them, and if you live in an urban area, you may even have access to Xfinity or CenturyLink fiber. Both competitors allow customers the option to bundle phone or TV service with their internet packages. In most cases, bundling with phone and cable gets you a better deal on all three.

As popular providers with widespread service, they are also more susceptible to customer criticism. A small provider that services a single ZIP code may only have a handful of negative reviews, but a large ISP serving customers nationwide is more likely to have complaints. Keep this in mind when viewing our company comparison, and read on to see a more in-depth breakdown of the two service providers.

I have had this company several times over the years and I have always ended up coming back to them. Great company with good customer services. You should always get the 2 year contract and try to get a renewal when the contract expires.

If I could rate CenturyLink a zero I would! The absolute worst internet provider I've ever had. Customer service is rude, hang up on customers and not helpful. Internet is down more than it works and they don't care. Not sure why it says Amazing for one star?! Disappointing and absolutely awful service and products!!!

They might have had a bad rep in the past, even with me but they are way faster and far more stable then my older internet provider and they have made it easy to get setup with faster speeds as needed, rent movies and add 3rd party services like Disney+ and even when internet is down due to repairs, they seem alot easier to get ahold of and figure this information out then they were just 5 years ago.

Spent hours on the phone and still don't have internet. I was supposed to get connected on the 1st tech left a hole in my wall uncapped and a drill in my yard along with drywall on the floor. I've been told that people were coming out on 2 different occasions for them not to show up or call. Worst experience, trying to get settled in my new address and was on the phone for 4:45 minutes this morning and over and hour the night before for me to still be in the same spot as before. So frustrated!!!!

The Final Word

As you might have noticed in the side-by-side comparison, CenturyLink and Comcast Xfinity have a wealth of differences.

They seem to share low customer scores, but keep in mind that customer scores are relatively low industry-wide. In CenturyLink’s specific case, its coverage area could be the reason for numerous one-star reviews. CenturyLink specializes in serving rural areas, which are unlikely to receive a high speed connection in the United States. 

As a result, more users have cause to complain about unreliable speeds and connection. Users in urban areas who can connect to CenturyLink fiber might have a more positive experience. Keep in mind, however, that despite CenturyLink’s large coverage area, the provider is the third largest in the United States, while Xfinity is the largest despite less surface area covered.

While both share some common customer service complaints, Xfinity is slightly less likely to have complaints of delivering lower-than-advertised speeds. For those prioritizing reliable internet, Xfinity could be the winner.

However, Xfinity has less of an edge with its contract. CenturyLink offers an internet Price for Life guarantee that will lock in your rate, and the company charges by the month. For those who move frequently and for customers who are wary of ISP contracts with cancellation fees and rising rates, CenturyLink may have the more appealing plan.

The better provider can also depend on your desired download speeds and price. Xfinity’s cheapest plan is $29.99 per month for 15 mbps. CenturyLink’s cheapest is $45 per month for 20 mbps. If you prioritize a plan with the fastest possible connection, Xfinity tops off at 2,000 mbps for $299.95; CenturyLink caps at 1,000 mbps. For 2,000 mbps, you could stream on dozens of devices to your heart’s content, but it will likely be overkill for the average household.

If you’re more inclined to a modest 1,000 mbps of internet, Xfinity is $70 per month and CenturyLink is $65. This is why the fastest and cheapest plans can be deceiving; consumers will likely settle with something in the middle, and sometimes CenturyLink offers a better rate.

Lastly, you might be juggling the issue of data caps. CenturyLink has 1 TB data caps on most plans (besides for business owners and users on a 1,000 mbps plan). Meanwhile, Xfinity caps everyone out at 1 TB regardless of plan.

The ISP of your dreams will depend on what you prioritize. For high speeds that deliver consistently, you may prefer Xfinity Comcast. For consistent pricing and an affordable 1,000 mbps, you might opt for CenturyLink service.
