TP-Link RE605X

The best overall — a WiFi 6 AX1800 extender with good coverage, a gigabit port, and TP-Link OneMesh support so it forms one seamless network with automatic roaming (paired with a compatible router), at a reasonable price. The backhaul penalty still applies and seamless roaming needs a OneMesh router, but the sweet spot of WiFi 6 speed, coverage, mesh capability, and value.

The TP-Link RE605X (AX1800) is a WiFi 6 extender that's genuinely fast, covers a good area, and supports OneMesh so it works as part of a seamless network rather than a separate one — at a reasonable price. It uses WiFi 6 (faster and more efficient with multiple devices than the WiFi 5 in cheaper extenders) at AX1800 dual-band speeds, extends coverage to a large area with a gigabit Ethernet port, and crucially supports TP-Link OneMesh — so with a compatible router it forms one seamless network with a single name and automatic roaming, solving the biggest extender frustration. It still has the inherent backhaul penalty all extenders share, OneMesh seamless roaming needs a compatible TP-Link router, and it's mid-priced, but for the best balance of WiFi 6 speed, coverage, mesh capability, and value, it's the one most people should buy.
