It also depends what else you are trying to do, but I love PiHole’s ability to act as a proper DNS server for my LAN with support for A and CNAME records

I migrated to Z2M about a year ago and I have had nothing but problems. Mostly around stability of Mosquito. I am back on ZHA now and find it infinitely more stable and reliable. If Z2M ever does a direct HA API integration like ZwaveJS does I’ll probably go back.
