AT&T’s fiber plan speeds range from 300Mbps up to 5,000Mbps for $55 to $155 per month. There are no contracts, and the monthly price includes router rental, installation, and unlimited data. 

Xfinity offers plans from 300Mbps up to 2,000Mbps priced between $40 to $100 per month. Xfinity is not all-inclusive, so you may be on the hook for hidden costs like your router rental, professional or self-installation, and additional or unlimited data. Xfinity is cheaper than AT&T at face value, but Xfinity’s cable connection makes its upload speeds much lower than download.

Speed and reliability

AT&T Fiber

4.0/5.0

Xfinity

4.3/5.0

AT&T offers fiber, fixed wireless, and DSL services. On the fiber side, the provider can get up to 8,000Mbps speeds, and the symmetrical download and upload speeds provide an overall smoother experience whether you’re streaming or uploading content. Meanwhile, Xfinity makes it onto Reviews.org’s Fastest Internet Providers report, which uses Xfinity internet speed test data. For a cable provider, this is impressive. Xfinity also offers up to 2,000Mbps download speed, which is more than enough for most families to carry out their daily internet activities.

Dollar value

AT&T Fiber

3.8/5.0

Xfinity

3.8/5.0

AT&T Fiber is available in 21 states, but it doesn’t pack as much speed per dollar as other fiber providers like Google Fiber or Metronet. Still, all fiber plans come with unlimited data, and there are no annual price increases, cancellation fees, router rental fees, or professional installation charges. On the other hand, you get a really good deal with Xfinity: Fast speeds, lots of data, and low prices for the first one to three years on a promotional term. However, after this promotional term is over, you can experience a price increase by $20 to $30 each month. That doesn’t happen with AT&T.

Customer experience

AT&T Fiber

4.0/5.0

Xfinity

3.3/5.0

AT&T has a great reputation for its customer experience. The provider takes first place in the American Customer Satisfaction Index (ACSI) Telecommunications Study 2024, beating all other fiber internet service providers for performance and customer experience. The provider also does well in HighSpeedInternet.com’s 2023 Customer Satisfaction Survey, scoring above average across speed, price, reliability, and customer service. Xfinity also scores above average in HighSpeedInternet.com’s survey across the board. However, the cable provider comes in sixth place in the ACSI Telecommunications Study among non-fiber providers. This places it behind even some 5G home internet services like T-Mobile and Verizon, which typically have more variable service than cable internet plans. In short, AT&T is the clear winner here.

AT&T Fiber

3.9/5.0

Xfinity

3.83/5.0

AT&T is a great internet provider, though you get the most bang for your buck out of its fiber internet service. It’s great that the provider offers fast symmetrical speeds and a reliable customer experience. The prices are more expensive than average internet prices, but you’re paying for a top-notch service that shouldn’t let you down.

Xfinity also performs well and gets fast download speeds for an affordable introductory rate. However, it’s never a favorable experience to see your bill rising while your neighbor signs up with cheap rates. 

Overall, AT&T is the better pick if you can sign up to its fiber internet service. The provider’s customer-centric approach takes the hassle out of calculating your final bill because everything you need is included in the plan. There are no price increases to be wary of, or charges for extra data. Although Xfinity gets fast download speeds, you can’t beat symmetrical speeds that make uploading social media posts and video calls a breeze.

AT&T vs. Xfinity: What do customers think?

AT&T Fiber

AT&T is a reliable fiber provider with stable prices.

AT&T customers are generally satisfied with their fiber internet service. “I would say their internet is reliable. It’s been relatively trouble free,” says Jane Collins, an AT&T customer who lives in the Detroit metro area. “The pricing has been stable,” she says.

While AT&T plans are tiered at specific speeds, you may be lucky enough to experience even faster download and upload speeds than advertised. “My advertised speeds are 300Mbps download and upload speed, but they’re very often faster than that,” says Lauren Hannula, who is a fan of AT&T’s fast and reliable network.

Not all AT&T customers think they’re getting the most bang for their buck. “I wouldn’t say it’s a good deal, but it’s comparable to the other ISPs I’ve used,” says Mike Hayden, an AT&T customer in Oak Park, Illinois. Hayden used to be an Xfinity customer, but now believes AT&T is the better provider in his town. While he has tried to barter down his monthly price with AT&T, he has yet to be successful. However, he did receive a $200 Visa gift card, a nifty outcome from his negotiation efforts.

“The pricing has been stable.” –Jane Collins, an AT&T customer in Detroit
Xfinity

Xfinity gets the job done, but its prices aren’t cheap forever

Xfinity customers have mixed experiences: Some customers run into outages, while others avoid any issues. “I’ve never had any real trouble with Xfinity,” says Bill Holmes, an Xfinity customer in Portland, Connecticut. “I’m one of those guys who tests their plans a lot to make sure I’m getting what I’m paying for. Overall, I’ve been very happy.” This contrasts with Bridget Gutierrez, an Xfinity customer in Albuquerque who frequently experiences outages. “It seems like every time I've gone up to the next speed, it didn't make a difference,” Gutierrez says.

Xfinity’s promotional prices last for only one to three years, so loyal customers feel like  it’s unfair that new customers get deals while they’re left with rising bills. “The downside is the prices would often jump around after a year, and we would either end up paying more or switch plans,” says Derek Marsden, an Xfinity customer in Farmington, Utah.

To take advantage of Xfinity’s deals for new customers, Holmes canceled his Xfinity internet plan and signed up again under his wife’s name. “She’s a brand new customer, so we got a two-year [deal] for $39.99 a month,” he says.
