I have been flip-flopping between so many different setups lately, but I have yet to find the one. I am currently trying Gnome out, and while I don’t think it feels as bad as I was led to believe there are a couple of niggling issues that keep me from committing totally.
I don’t know what I would consider the best of any of this stuff right now. I’ve used so much and none of it has ever stuck with me for very long, even when I was a teenage tinkerer decades ago. I’m so indecisive! I really like what NixOS/Guix System are doing but I don’t think I could in good faith recommend either for anything to anyone as it stands despite my own frequent wall-to-head ordeals in trying to daily driver Guix. Declarative, transactional systems absolutely feel like future shit to me, but I would not call the UX at all very pleasant; maybe it never will be. That’s unrelated to WMs and DEs though. I feel like of all the things i3/sway were, so far, my favorites there.
