I've been a xmonad user for a long time, but I'm going to switch to i3.
While xmonad is nice, and haskell is nice, the haskell eco system is a PITA. And things break a lot(using cabal). And somehow, after a long time of no changes my xmonad will no longer recompile. Trying to update the haskell stuff just turned out to be a HUGE pain. Also the libraries take up way too much space because you have to have then in different ways. I forgot how it went, but having xmonad(a small wm) required something like 1 to 1,5gb of harddrive space.
