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.

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.
