I was an ESXi fan for over a decade until I found proxmox.
Now I use a combination of VMs and Linux containers.
I use containers for:
Pihole, Ubiquity WiFi Controller, Plex, Audio Bookshelf, imfluxdb, etc. And VMs for Home Assistant and Untangled.

I'm glad you enjoyed it! I've never looked back, it's a wonderful change.
