I use only atomic distros now and could not be happier.

Presently using Fedora Atomic Cosmic, it’s minimal, stable, quite beauttiful and does everytihng I need it to. Just as Silverblue did for a long time, just thought I’d switch it up and trial Cosmic long use. I imagine my needs are less than some, am not a gamer

The only package I layer is Opensnitch. Flatpaks and a couple appimages covers all else,

I have no idea what customization or anything else I am told I’m missing out on, and that’s fine by me, guess better I can’t miss what I don’t need ;) For me personally, 100% feature complete. Though I would guess gaming needs would be a different situtation/needs, so cannot comment on that
