I used the big ones, ubuntu, arch, opensuse and (atomic) fedora. Fedora had the nicest out of box experience. Morover, I moved to podman, systemd, selinux, etc. And the atomic version showed me a new workflow with flatpak and distrobox (nowadays, I use nix oftentimes).

The best part about it is that I do not care about the system anymore. I do not even interact with it. I don't install packages (besides the base layer and minimal modifications that are long lasting like installing openssl for GNOME iirc)

I use mainly flatpaks, if I need aur, I fire up distrobox, or use nix if I want to. And the best part is, I'd have the exact same workflow even without the atomic version. Even on another distro. I do not interact with it much.

Moreover, I am happy with all the choices fedora made with the base package and images. I do not have to do an informed choice like on arch. It just updates whenever I boot my pc. I do not need to read updates, they are just there, somewhere. I do not need to disable snaps or work around weird choices. I just start firefox, vscodium, a terminal and do whatever I want to do.

Edit: I actually wanted to switch back to opensuse just to support it but I guess I'd rather move to nix some day. Maybe with niri and cosmic.
