IMO Thread has one major benefit over Zigbee: the Thread mesh can extend over Ethernet (via TREL). Zigbee ought to be able to do this too, but I’m not aware of anyone actually doing it.

There are a couple of in-progress implementations of Zigbee on a regular computer using Thread radios and the Thread RCP protocol. Maybe one of them will add the ability to use multiple radios.
