I moved home assistant from a raspberry pi 4 to a NUC a few years back with a few other services (ZigBee, mqtt, etc) and it’s been fantastic. I’m also running frigate on the same system with a Google Coral for object detection and it handles the load of several network camera feeds well.

I use OpenRC on most of my systems, which honestly works well enough that I’ve never felt the need to change. SystemD at work though, which is also fine. If I have any complaints, it’s just not what I’m used to.

Switching could be tricky, and may not be worth the hassle. It’d really depend on what you want to get out of it. As always though it’d be a good way to learn as you’ll inevitably break something and need to figure out how to fix it.
