Currently running fedora, because it is stable, easy to use and just works.
Also, gnome is imo the best designed major, full-featured desktop environment that exists out there (even including windows or macos).
You might get a more tailored experience with window managers but im currently to lazy to set that up. I did use dwm for a time though, but it wasnt really flexible enough for me.
Dwm is literally the most flexible wm imaginable, its just not for everyone. The intention is that the codebase is so small that you can just program whatever you want (or download patches from others and do your best to make them all work together)
