People are trying to switch to proxmox too since VMWare continues to go downhill and smart IT planners know you shouldn't trust them long term.
I use proxmox in my homelab so my impression is biased as a home user, but it's nice if you're already accustomed to being a Linux command line user. They haven't fully made everything configurable through the GUI. 90% of the time you can use the GUI but for certain things it's still command line only.
