The models' case: easiest setup and management, Wi-Fi 7 at a mainstream price, strong smart-home integration with Matter, Thread, Zigbee, and backward-compatible eero expansion. The models' main caveat: add a 6GHz band without forcing buyers up to eero Pro 7. The strongest alternative is TP-Link Deco BE23 — best value by far, three Wi-Fi 7 nodes well under $400, strong long-range throughput, 2.5GbE ports, easy Deco app, enough coverage for most large. Not unanimous: ChatGPT picks TP-Link Deco BE23; Claude picks TP-Link Deco BE63.
