Choosing between Xfinity and Fios comes down to the plans offered at your address. Verizon describes Fios as fiber to the home, with nearly equal upload and download speeds on most plans. Xfinity's service is powered by fiber in its network and reaches the home over coaxial cable, though Comcast now sells symmetrical tiers in some areas. Connection type is a starting point, not the answer. Compare each available plan's Broadband Facts label for typical speeds and data allowance, then confirm the offer with the provider before you switch.
Short answer: Verizon Fios if you can get it; Xfinity if you cannot
Where Verizon Fios actually reaches the property, it is the better connection — fiber gives you upload speed that matches download, and that is the difference people feel on video calls and cloud backups rather than on a speed test. Xfinity will usually reach more addresses in the same city, and its download speeds are competitive. So the question is almost never which is better in the abstract; it is whether Verizon Fios has been built to your street yet.
- Verizon Fios is fiber to the home, operated by Verizon Communications Inc.. Xfinity is cable, operated by Comcast Corporation.
- Verizon Fios: plans commonly range from 300 Mbps up to 2 Gbps where available.
- Xfinity: plans commonly range from 150 Mbps up to 2 Gbps where available.
- Both operate in 3 of the markets FiberNear tracks, so this is a real choice rather than a hypothetical one in those cities.
- Both are built out address by address. Whichever reaches your specific property usually settles the question before preference does — FiberNear checks that free.
Verizon Fios vs Xfinity, side by side
| Verizon Fios | Xfinity | |
|---|---|---|
| Connection type | Fiber to the home | Cable |
| How it reaches you | 100% fiber-optic | Hybrid fiber-coaxial cable, with fiber to a limited set of addresses |
| Speeds | Plans commonly range from 300 Mbps up to 2 Gbps where available | Plans commonly range from 150 Mbps up to 2 Gbps where available |
| Where it runs | The Northeast and Mid-Atlantic, from Virginia up through New England | Around 40 states, concentrated in the Northeast, Mid-Atlantic and Midwest |
| Known for | Consistently strong reliability scores and symmetrical upload speeds | The widest gigabit-capable cable footprint in the US |
| Operated by | Verizon Communications Inc. | Comcast Corporation |
Speeds and footprints are advertised by each provider, vary by address, and change without notice. FiberNear does not set or guarantee them.
Xfinity or Fios: how to compare the full offer
Compare the two offers you can actually order, not headline numbers. Every plan's Broadband Facts label separates the monthly price from additional charges, says whether that price is introductory and what it becomes afterward, and shows the contract length if one is required.
Equipment and data terms belong in the same comparison. Verizon says all Fios internet plans include router rental at no additional cost. Xfinity says its current plans include WiFi equipment and unlimited data, with no annual contract. If you already have Xfinity on an older plan, check your account: Xfinity says legacy plans may still carry a 1.2 TB monthly data limit.

Gigabit fiber and multi-gig speed tiers: Verizon Fios vs Xfinity side by side
Both networks publish tiered plans, and the tier class matters as much as the top-line speed. Here is what each side offers as a tier, based on the plans each provider currently advertises.
- Verizon Fios offers multi-gig fiber, up to 2 Gbps advertised where available.
- Xfinity offers high-speed cable, advertised up to 1 Gbps on the top tier where available.
- Only Verizon Fios is fiber, so its gigabit tier delivers matching upload speed. Xfinity's advertised gigabit tier is a download figure, and its upload runs materially slower on the same plan.
- Tier availability varies by address. A multi-gig plan advertised in a market is not offered at every address inside that market, since it depends on whether the local optical distribution supports it.
Tier classes are derived from each provider's own advertised plans and change without notice. FiberNear does not set or guarantee speeds.
If you can get both Xfinity and Fios, how should you choose?
Start with upload speed, because that is where the two networks have differed most. Verizon says Fios offers nearly symmetrical upload and download speeds on most plans, and lists Fios 1 Gig at up to 940 Mbps down and up to 880 Mbps up.
Cable no longer means a slow upload everywhere. In December 2023 Comcast began rolling out DOCSIS 4.0 in select neighborhoods, with symmetrical X-Class tiers from 300 Mbps to 2 Gbps. Xfinity says those speeds are available in limited areas and that customer-owned modems do not currently work with them. A rollout announcement tells you nothing about your street, so check the Xfinity offer for your address.
Then read the labels. Each one lists typical download speed, typical upload speed and typical latency. If the Xfinity plan meets your needs on those figures and its terms suit you better, it is a fair choice even though it runs on cable.

Where Verizon Fios and Xfinity overlap
These are the markets FiberNear tracks where both networks operate, so the comparison is a real decision rather than a hypothetical. The percentage is the share of each city's residential locations reached by fiber of any brand, from FCC filings — it describes the market, not either company's own footprint.
| Market | Fiber available | Cable available |
|---|---|---|
| Boston, MA | 69.8% | 99.5% |
| Philadelphia, PA | 86.2% | 99.0% |
| Washington, DC | 62.4% | 97.6% |

How often each one is actually available
Specifications decide which connection is better. Availability decides which one you can buy, and it is the part comparison pages usually skip. Across the 29 markets FiberNear holds FCC data for, this is how much of each city the two technologies reach at 100/20 Mbps or better:
- Verizon Fios is fiber, and fiber reaches a median of 64.2% of locations in a typical tracked market.
- Xfinity is cable, and cable reaches a median of 96.2%.
- So in a typical market, Xfinity's technology reaches about 32.0% more of the city — which is why the comparison so often ends up being decided by the address rather than by the plan.
Source: FCC Broadband Data Collection, residential fixed broadband, as of December 31, 2025. Figures are advertised availability self-reported by providers, not measured speeds. These are technology-level figures, not brand-level ones — the FCC's public summary files report how much fiber or cable reaches a city, but not which brand owns it, so no coverage percentage here should be read as a figure for Verizon Fios or Xfinity specifically.
