Verdict: Google Fiber delivers true symmetric gigabit speeds with latency as low as 10 ms (CNET) and no data caps, making it superior for gamers and remote workers. Xfinity’s top tier reaches 1.2 Gbps down but only ~35 Mbps up and imposes a 1.2 TB cap (Tom’s Guide), which can hinder heavy upload tasks. While Xfinity benefits from broader coverage and lower entry pricing, the latency and cap advantages give Google Fiber the edge for power users.
