On Desktop I am perfectly happy running Debian sid again after a long detour to Mac OS X until it got enshittified too much. Ubuntu is interesting for enterprise use though, the microcloud and LXC/LXD stuff is at least worth considering if starting to build things up on bare metal. Containers are relatively easy with Nomad/K8s, but if you want to spin up your own VM layer (OpenStack?) then I would consider Ubuntu before going to Nutanix and others
