I settled down for Fluxbox back when it was still actively maintained. Ever since its death I have been using IceWM, mostly because it is so much faster than GNOME or KDE-Plasma. I think both KDE and GNOME went into the wrong direction though. GNOME because it forces everyone into the shell-centric way to use a computer, similar to a smartphone (the whole UI constantly reminds me of a cloned OSX smartphone interface, for GNOME3 that is; mate-desktop is more of a desktop-centric UI but sadly the project slowed down immensely in the last few years, aka becoming more and more inactive really). KDE indeed has too many configure-options, but the defaults are more similar to the 1990s desktop-centric era shaped by Microsoft. I like that approach more than GNOME although in the last few years KDE also went the wrong way, largely due to Nate, David Edmundson ("our destiny is systemd"; that reminds me of Firefox "you must have pulseaudio for audio on youtube", how strange I can hear audio via chromium/thorium just fine, so what are the Mozilla devs thinking here ... not much, that is for sure) etc...
