I currently have a SmartThings Hub and Homeassistant Yellow, but if I were starting over today, I'd be all in on Matter (mostly thread) and avoid ZWave and Zigbee outright. I'm mostly stuck to zwave because of my blinds, but I think I will slowly replace all my smart home related things with Matter.
There's still a few sensors that there don't have a Matter equivalent yet, but I think that'll change soon.
