Ok, you don't like XMonad or Haskell, fine. I use XMonad daily. It has a giant pile of contributed modules, it's extremely flexible and used by a reasonable amount of people. I can give you one reason for not i3, ratpoison or dwm: as far as I know, they are all manual tiling WM (no notion of "master" window like XMonad). They're still tiling WMs, but of a different breed.
