Xfinity vs Ziply Fiber in Mill Creek

Mill Creek’s trade-off is Xfinity’s broad cable availability versus Ziply Fiber’s lower price and dramatically faster fiber uploads where available.

The 30-Second VerdictUpdated September 21, 2026

Ziply Fiber is the better overall pick in Mill Creek because it combines lower starting pricing with much faster download and upload speeds, while reaching about as much of the city overall as Xfinity. Ziply wins on speed and price, while coverage is essentially a tie at about 96% citywide. Xfinity is the sensible choice for shoppers who prefer cable or find its service at their address, with speeds up to 2,000/300 Mbps where available. Ziply Fiber fits households that game, work from home, upload files, or want the strongest performance for $20/mo.
