Xfinity vs Ziply Fiber in Kirkland
Kirkland shoppers trade Xfinity’s broader reach for Ziply Fiber’s lower starting price and dramatically faster, symmetrical upload performance.
Ziply Fiber is the better overall pick: its $20 starting price and 6,000/6,000 Mbps fiber plan deliver far faster downloads and uploads where available. Xfinity reaches about 99% of Kirkland, compared with about 95% for Ziply Fiber, but its upload tops out at 300 Mbps against 6,000 Mbps on Ziply Fiber, so weak upload gets less weight. Ziply wins on speed and price, while Xfinity wins on coverage. Choose Ziply Fiber for gaming, video calls, and heavy households; choose Xfinity if reaching more addresses matters most.
