Quick verdict
The Z-Stick 10 Pro is the one dual-radio stick worth taking seriously: a Z-Wave 800 Long Range radio and a Zigbee 3.0 radio in one USB-A body that shows up as two serial ports. Z-Wave JS takes one, ZHA or Zigbee2MQTT takes the other, and owners report both running together. The catch is that it behaves like two products in one shell. Aeotec's own guide says so, and the Zigbee side has needed a manual firmware update to 7.4.3 before Zigbee2MQTT's ember driver would talk to it. If you are happy doing that once, it saves a USB port and about the cost of a second coordinator. I haven't run this one; the notes come from the spec sheet, the Home Assistant integration docs and what other owners report.
Standout: Z-Wave 800 with Long Range (EFR32ZG23) and Zigbee 3.0 (EFR32MG21) on one stick, presented as two serial ports so Z-Wave JS and ZHA or Zigbee2MQTT can run side by side.
