FYI, using ZHA or Zigbee2MQTT does not affect if a device will drop of the network more or not if usibg the exact same Zigbee Coordinator chip model and firmware version as the Zigbee network is managed by the Zigbee stack running on it.
What will affect connection other that the device that that have problems is amount, type and location/placement of Zigbee Router devices as well as EMI/RMI/EMF interference (which also includes Zigbee channel uses).
If you use the exact same Zigbee Coordinator and Zigbee devices in the exact same location then the mesh network topology and stability of the connections would be exctly the same in ZHA or Z2M.
So that should not be reason for moving from the ZHA integration to Zigbee2MQTT or vice versa. See:
