I run Silverblue on 2 devices (my main computer and laptop) for half a year. It works and I didn't have any major issues with it. Though as you might have experienced with other immutable distros, some things like configuring gdm might be a bit more work. But for most things there is a flatpak. The only software that couldn't be installed that wat was my vpn.

If you want to try out something new, NixOS or Guix might be more up your alley
