I've dabbled in at least trying the absolute basics of the popular DEs. Cinnamon, KDE, Gnome, whatever Ubuntu's current thing is called, Pop's Gnome spinoff, XFCE. Think I tried Budgie for like a minute too.
The one I stuck with the longest was Gnome on Manjaro.
Otherwise, I kind of like them all in their own way. The only reason I left Cinnamon in the first place was ~4 years ago I had this bug where switching virtual desktops by the arrow shortcut would get progressively laggier.
