XFCE was my favorite back in my Gentoo days, after I started using laptop hardware fast enough that it wasn’t noticeably slower than my prior favorite, WindowMaker :-)
When I used early Ubuntus on desktop machines (back when Ubuntu wasn’t terrible—before the PulseAudio fiasco and the following series of bad decisions and failed maneuvers against Red Hat) I usually just stuck with the default of Gnome2. That era’s by far the closest I’ve seen Linux get to Just Working.
[edit] FWIW I do find Void with a very-light window manager pleasant to use, but I don’t want to have to self-serve every little feature these days, so it’s pleasant but impractical for my actual life. Nothing short of a full DE, so just KDE or Gnome, with a batteries-included distro, stands a chance of matching what I’m used to just being there and happening for me without my having to ask for it. Unfortunately, I strongly dislike both of those DEs for different reasons. :-/
