KDE on Mandrake/SuSE back when they were on version 1/2, GNOME on Debian/Ubuntu until 2016, a little bit of Enlightenment for the quirky days, XFCE instead of Enlightenment when I had to do actual work on a lighter machine, and now have been using GNOME daily for 4-5 years. For me it's customizable enough, and I prefer the design to KDE these days (KDE has too many different margins and paddings for me to handle).
