Maybe my use case is abnormal, but I allocate the majority of my resources to a primary VM where I run everything, including containers, etc. but by running Proxmox now I can backup my entire server and even transfer it across the network. If I ever have some software to try out, I can do it in a new VM rather than on my main host. I can also ‘reboot’ my ‘server’ without actually rebooting the real computer, which meant less fan noises and interruption back when I used an actual rack mounted server at home.
