Omarchy's one of the three OSs that I tried today on an Ubuntu 26.4 VM host. I was a quick install but if felt a bit rough, like driving a tractor. I also got in trouble when I tried to bring up the Display Settings and screwed things up. Not ready for prime-time, in my case anyways. Probably was my inexperience with arch distros.

Also tried LordOS very quick, very easy to install, looks and feels like macOS, but Debian distro underneath.

I also tried GhostBSD. It's easy enough to work with, but it does not have any packages for "spice-vdagent," which I needed to resize the screen size and clipboard copy/paste support between host and guest devices when using Virt Manager :(
