@hans_w Agreed one choice of a WM/DE is probably the most personal choice one can make on linux and effects some pretty core things about how you use the system.
I started on KDE and GNOME like most people but I quickly learned about minimal WM's like fluxbox and at a time where computer resources were more limited. For a while I stuck with minimal but tranditional WM, xfce4 and fluxbox mostly back in the day.
Once I discovered tiling window managers though I never looked back. First I moved to QTile that i heavily customized myself and now for the past few years ive been using i3-gaps fairly exclusively on all my systems
