it probably doesn't matter, but i run debian (sid).
i used to distro hop, and i think i've probably tried every DE and WM available as a deb so i'm vaguely familiar with most of them. and i used to use cwm exclusively, and then dwm, but ended up on xfce somehow.
@zacanger I'm pretty happy with i3wm. I switched from xmonad because needed running ghc for my wm config annoyed me, and because I found the tab support in xmonad flaky. The latter might be fixed.
i3wm is much more focused on manipulating a current window layout than snapping between predefined ones. Depends what you like, I guess, both have their merits.
