If you plan on gaming on atomic Fedora it is basically just that with everything already preconfigured. I chose it because it came with Nvidia drivers, codecs, a bunch of tweaks and gaming utilities preinstalled (protonqt, distrobox, lutris, etc)

You could install all of this on Fedora but IMO it’s convenient to just have everything already configured for you if you were going to do it anyways

I also like that it is atomic. Builds on the same image tag guarantee an identical build, which completely fixes the “works on my machine” problem when helping my friends. Two users on the same release will never have mismatched shared libraries or rogue packages, everyone on the same tag has the exact same environment. Plus, it makes rolling back bad upgrades incredibly easy
