I use proxmox for basically anything in my homelab, but there’s no particular reason. I use it because it does what I need. It supports VMs in case I need a bit more control over what runs in the system (like a Windows VM) and it supports LXCs that fundamentally work like docker with less configuration steps. It provides a nice webUI if I need to check up on some things and an API so I can orchestrate all my systems with terraform.

It does the job and I never saw a reason to switch away from it.
