Since I mostly use computers for entertainment these days I keep coming back to Bazzite. It’s fast, stable, kept up to date, reliable, and “just works”. I’ve created custom rpm-ostree layers to faff around, but it’s not actually necessary for anything I need.
I used to keep a second Kubuntu Minimal partition around but I realized I just don’t need it. If I wasn’t so happy with Bazzite, I would probably go with openSUSE or Endeavor.
