i used KDE4 for a long time after i switched away from gnome 3 because was just so restrictive and difficult to tweak and use. I really liked kde4 but ultimately switched away becasue it was heavy and i didn't like many of the kde version of applications. I preferred the gtk based apps. Now I use Enlightenment DR17 because it is lightweight, fast, and looks great. Its a bit difficult to install sometimes becasue its not a stable release yet, but as i am on gentoo, installing from source isnt really a problem.
