All the three products are designed with the same ax1800 wifi-6 technology; each radio band delivers the same wifi speed technically.

High gain antennas

Mercku M6 comes with patented WHEMS high gain antenna, the internal antenna design with 5dBi high gain antenna; that is strong enough to cover up to 3,000 sq ft each unit. In general, most internal antennas are usually designed with standard 2 or 3 dBi gain. You can compare that with the Deco x20 which can only cover up to 4,800 sq ft for 3 nodes. While Asus xda covers up to 4,800 sq ft for 3 nodes. Note that those are technical coverage; they might be different in the real world.
