Fedora. Used to use Arch but it broke and I moved to Fedora, it's a way more polished experience. I like how Fedora is stable but not "stale" like Debian. Want to try Fedora Silverblue as well.
I highly recommend silverblue! The only thing that can be frustrating is Steam and other game related things, particularly with wireless controllers it seems. But overall it makes it very hassle free imo.
What specific problems are you having with steam? I am using the flatpak version (configured with flatseal) and it has been working flawlessly. Are you using the rpm version?
