Been loving vim for several years. Finally decided to learn emacs, partially spurred by interest in clojure.

It seems that as more languages are created that include native repl experiences, emacs becomes more appealing to me because it fits nicely with editor+repl, where in other editors a repl seems more of an afterthought or nice-to-have.

I would say definitely learn vim first, but it's great to know both vim and emacs. It just opens up more doors.
