Astound vs Xfinity in San Francisco
San Francisco shoppers trade Astound’s narrower availability for Xfinity’s broader reach and faster upload potential at the same starting price.
Xfinity is the better overall pick because it reaches far more San Francisco homes and offers faster downloads and uploads for the same $40/mo starting price. Xfinity wins on speed and coverage, while price is a tie; both have a 91/100 speed score. Astound is a reasonable choice where its service reaches your address, especially if you only need everyday browsing and streaming. Choose Xfinity for broader availability, gaming, work-from-home, or heavier household use; choose Astound when its local availability fits your needs and you do not need the fastest uploads.

Rank score (0–100) is each provider’s Speed Score, discounted for weak upload, times the share of that ZIP it reaches — the same rule that orders providers on the San Francisco city page, so it moves as availability changes street to street.
