I also made a very similar comment, but with uBlue (Bazzite, Aurora, Bluefin) instead.
They are still pretty vanilla, but include a big list of QoL stuff added in, like staged updates, Distrobox, a huge list gaming tweaks in Bazzite, and much more.
It’s basically stock Atomic made right!
I’ve used them for a year now, and they’re fantastic!
Just a small heads up for OP: You have to do quite a lot of (advanced) things differently from now on if you choose Atomic. Use containers (Distrobox, etc.) for everything you can, avoid installing stuff on the host if possible, etc.
