Nabu Casa hardware

The first-party hardware from the people who make Home Assistant. These aren't alternatives to each other: one runs Home Assistant, two add a radio to it, and one is a voice endpoint for Assist.

Which one to buy

Start with the Green if you want Home Assistant running without assembling anything; it's the easiest on-ramp, and heavier add-ons like Frigate may eventually outgrow it.

Add a Connect ZBT-2 for Zigbee or Thread (it runs one of the two at a time) and a Connect ZWA-2 for Z-Wave; the ZWA-2 is Z-Wave only, so a house on both radios needs both sticks, and the ZBT-2 has been out of stock at every channel on recent checks.

The Voice Preview Edition is for local wake-word voice through Assist, and it's voice-first hardware, not a touchscreen.

I own and have tested Home Assistant Connect ZBT-2 (5/5) and Home Assistant Voice Preview Edition (3.5/5). I haven't run the others, so those picks are based on the spec sheet and what other Home Assistant users report.
