i use the universal blue silverblue-main image because it’s basically silverblue along with some packages included that I otherwise would have to manually layer in anyway (e.g., distrobox, freeworld-amd drivers from rpmfusion) and some quality-of-life improvements (some just recipes, automatic updates enabled)
I tried bluefin, but it was “too opinionated” and I didn’t agree with a lot of its opinions. Same for bazzite.
