Oh gawd, I spent so much time looking at that site and searching for the "best" wm. As my main WM, I've used fvwm (which I think was the default on slackware back then), olvwm (since I was used to Sun Unix machines from a summer job...), afterstep/windowmaker (NeXT was cool), fluxbox, kde 1.x-3.x, xmonad.

Nowadays I'm just using gnome with pretty much default configs.
