Both are manual tiling window managers. I tried i3wm and I didn't like it that much, though. StumpWM is essentially Ratpoison reimplemented in Common Lisp. It's really good and stable, plus it resembles Emacs a lot. There's even a winner-mode. There's not much to say except that you can tweak it till infinity and extend it in CL. But for me most defaults are pretty good already.
