Is the Aqara M3 a good general-purpose Zigbee hub?

Reviewers are split. Specialist Aqara community threads we read repeatedly caution that the M3 works best with Aqara's own Zigbee devices and that several headline features arrived late or incomplete. It's a capable Matter controller and Thread border router, but consensus is it's not the strongest choice as a universal third-party Zigbee hub.
