- Xfinity and Fios are two of the most widely-recognized Internet providers in the US.
- The big differentiator is that Fios has a newer 100% fiber network while Xfinity uses an older cable network. Fios wins on speed, while Xfinity adds value with hard-to-beat TV offerings.
- In areas where they overlap, they compete heavily on price and quality of service. This is great for customers, who benefit from record-low promo rates.
We’ll get into the nitty-gritty of spec differences between Fios and Xfinity below.
Here are some quick picks for those of you who want a recommendation ASAP:
Verizon Fios: Recommended For Techies, Gamers, Cord Cutters & Home Offices

Verizon Fios has two key strengths: gigabit speeds and unlimited data use. They’re a perfect fit for heavy Internet users like techies, gamers, and remote workers who need the absolute best quality of service.
Their unlimited data policy makes them very friendly for streaming video content from services like Netflix and Hulu. The Fios fiber network is much better suited than cable to intensive upload-heavy applications like Skype and Twitch.
XFINITY from Comcast: Recommended For Family Homes, Budget Shoppers & TV Fans
- family homes
- budget shoppers
- tv fans
Xfinity competes strongly on bundled and budget services, making them a great choice for families that need a diverse mix of services (cable TV, Internet, phone, home security, etc) for an affordable price.
If you spend more than 20 hours weekly watching TV, you’ll benefit from their X1 smart TV platform, which is an industry leader in terms of channel count and on-demand content. As an added bonus, Xfinity is usually fast and simple to have installed or activated.
Key HighlightsFios is Fiber: Verizon Fios’s fiber network allows them to offer blazing fast broadband speeds up to 1,000/1,000mbps. These speeds are only matched by other residential fiber providers like Google Fiber.
Symmetrical Plans: Fios just recently upgrade all of their “Fios Quantum” internet plans to be “symmetrical” which means they offer the same upload speeds as their download speeds. This means if you work from home, do video conferencing, or upload large files often, you’ll see a huge boost in some of the tasks you do.
Solid Deals and Bundles: Verizon Fios is typically a little more expensive than Xfinity, but if you are comparing bundles and triple play plans you can find cost-effective solutions.
Fiber vs Cable for Internet Service
If your core need is high-speed Internet, Fios is generally the best choice.
Cable is fast enough for most people, but even the more expensive residential plans fall short on upload speeds and ping compared to Fios.
Packet loss on video calls and difficulties streaming on Twitch are common issues with cable connections, if only during peak use times (usually 5–7pm, varies by area). Fiber makes these issues much less common.
I’ve personally used both services in the past couple years, and while I’ve had a good experience with Comcast (aside from the confusing call center), Fios was ultimately most worth the money for the high standard of service and unbeatable upload speeds. Previously, I had been consistently getting throughput around 3/4 of the advertised “speeds up to” download rate. I had also been having issues using Skype and other conference call platforms. After switching to Fios, those problems virtually disappeared — presumably mostly thanks to the high upload speed and reduced latency.

Personal Experience and Speed Test Results
To demonstrate the speed differences between Comcast Xfinity and Verizon Fios, I asked a friend who was switching between providers to record a speedtest from both companies using the same server, same computer, and same time of day. Below is the video of the results:
As you can see from the video, Verizon Fios’s 150/150mbps plan, one of their middle plans, is still faster than Comcast’s fastest plan. Not to mention the upload speed with Verizon Fios is 32 times faster than with Comcast.
Note: Comcast has increased their plans since the above video was recorded. (Sept 2015)
Comcast Xfinity vs Verizon Fios Download Speeds
While Fios is theoretically much faster than Comcast, the popular plans from both providers fall into the same general download range — around 100 Mbps, depending on current promotions and service area.
The difference that matters for the average Internet user is that Fios delivers upload speeds equal to download speeds, while Comcast delivers lower upload speeds (usually in the 5–25 Mbps range).

Cable vs Fiber: Fios’ Fiber Network Wins Hands-Down
Comcast Xfinity is cable. Verizon Fios is fiber. What’s the difference?
The short answer is that fiber is a newer technology that’s much faster than cable. The long answer is a bit more complicated.
Cable Pros and Cons
Cable companies like Comcast deliver Internet via coaxial cable networks originally built for traditional subscription TV. Transmitting digital data over these “analog” networks is difficult, but thanks to advances in technology it’s possible to do so surprisingly well.
The caveat with cable is that coaxial cables weren’t built with uploading in mind. They’re great at carrying data (namely, TV channels) to the customer, but not good at carrying data back. As a result, upload speeds are generally between 5–25 Mbps, even on top-shelf “300 Mbps” plans.
Because data has to be modulated into analog signal on cable, ping also tends to be higher, which can create a lag effect on video calls and games.
Fiber Pros and Cons
Fiber cables, meanwhile, are designed specifically for digital data. Rather than modulating frequencies, fiber cables transmit data as light — which as Einstein established last century, is about as fast as you can get. Fios runs fiber all the way to the home, resulting in a maximum speed that is several times that of Xfinity.
Since the cables are designed for two-way transmission, the upload speeds match the download speeds, which makes a huge difference for gaming, streaming, and video communication.
Xfinity and Fios Coverage Areas
Fios may win the speed game, but Xfinity crushes them when it comes to availability.
Because fiber is so expensive to install ($50,000/mile according to some analysts), Verizon has been extremely slow to roll out extensive coverage. In fact, they even got sued by New York City in March of 2017 for failing to do so quickly enough over a multi-year contract with the local government.
The point is: Xfinity is practically ubiquitous, which can make it a good choice for those of us who move frequently and like to carry our service and home networking equipment with us.

Comcast vs Fios Customer Service
Comcast is well known at this point for mixed customer service experience and confusing fees. Since they rebranded as “Xfinity” things have improved somewhat, and the company seems determined to improve their public image as competition from Verizon and other Internet providers increases.
While the call centers might be confusing, they also offer an opportunity for customers who are willing to put up with it. Monthly fees creeping north? Try calling and negotiating a better deal.
Cable providers like Charter Communications generally refuse to work with customers on pricing, but Comcast has a history of giving good deals for long-time customers who bother to ask. Just be polite when you call, and be sure to remind them that you can switch if they can’t help you. (Assuming you actually can, that is.)
Fios has a somewhat better reputation for customer service, but they also have a reputation for taking longer than average to take care of issues. Be aware of this for installation in particular, since depending on demand you might have to schedule your installation as much as a week in advance.
Equipment and Installation: Fios Can Be Tricky
Overall, the installation process for Xfinity and Fios is much like the final product: Xfinity is cheaper and Fios is more expensive. (Unless you sign on for a multi-year contract, in which case either provider will usually throw in installation for free.)
You’ll need to budget more time for Fios installation, and it’s less friendly to bringing your own modem/router and home networking equipment into the mix.
Installation Considerations and Fees
Comcast installation usually means just hooking up a modem to the cable jack in your living room. Our suggestion: save the installation fee and do it yourself.
Fios is a bit more complicated, and requires a specialized terminal box called an ONT (Optical Network Terminal). If Fios hasn’t served your residence before, you’ll have to schedule an appointment with a technician when you sign up.
The Fios installation itself can take as long as eight hours depending on the layout of your home and the amount of in-home coaxial wiring needed. Long story short: plan to spend an entire day getting your home network situated.
Both Fios and Xfinity charge installation fees, but some customers have reported success arguing their way out of them with Xfinity if they’re able to do at least part of the installation themselves (or are willing to sign a long contract).
Fios also waives the installation fee for many of their multi-year contract plans.
Modem and router leasing fees
Xfinity and Fios both charge an extra $10 fee for leasing your “gateway” modem/router equipment. The difference here is that Xfinity makes it much easier to buy your own equipment elsewhere and save the monthly fee (which adds up to hundreds pretty quickly).
You can get ideas about which modem/router to buy at Xfinity’s approved cable modems page.
Using your own equipment with Fios is a bit more difficult, since they actively discourage it. Needless to say they’re still happy to charge $10 for their branded router.
In spite of their protests, many customers will find they can do more with their home network if they use their own equipment. We’ve covered how to work around their system and use your own equipment in-depth on our Verizon Fios deals page.
Bundle plans: Xfinity Has the Best TV DealsXfinity generally offers the best value bundled TV/Internet deals, which makes sense considering they started as a cable TV company. Their X1 platform brings a lot of on-demand functionality and advanced features into the mix. If you’re a TV buff, check out the details on our Comcast Xfinity page.
Conclusion: Fios Wins Overall, but Xfinity is Innovating Fast
At the end of the day, the “problem” of choosing between Fios and Xfinity is a good problem to have. If you’re a techie or a cord cutter, definitely opt for Fios. Xfinity makes more sense for TV fans and budget-minded family homes.
There are millions of Americans who only have access to one high-speed provider, so the fact that you have competition in your area means that Fios and Xfinity have to work harder to keep you as a customer.
