Xfinity vs Ziply Fiber in Kirkland
In Kirkland the real choice is Ziply Fiber’s cheaper, symmetrical up-to-6-gig fiber versus Xfinity’s near-total citywide cable coverage that reaches a few more blocks.
Ziply Fiber is the stronger overall pick in Kirkland where it reaches you: it’s cheaper at $20/mo, faster on paper at up to 6000/6000 Mbps, and posts a 99/100 speed score with symmetrical upload. Xfinity’s edge is reach, with ~99% coverage versus Ziply’s ~95%, plus a still-excellent 95/100 speed score and up to 2000/300 Mbps. Choose Ziply for the best price and symmetrical fiber speeds if your address qualifies. Choose Xfinity if Ziply hasn’t wired your block yet or you want the widest availability.
