I used to use KDE2 back then, I loved that you could set different Windows decorations for each Window (or is my memory tricking me?) and have a global menu bar optionally.
I did not like KDE3 as much bc they removed these features and ended up with GNOME2, and eventually MATE.
PS: I think it was GNOME 1 with the sawfish window manager. KDE2 did support theming the windows decorations, but on second thought, I don't think one could set different looks per window.
