Vim or Emacs, it doesn't really matter. Users of both will tell you that their editor is best, but if one was really better, we probably wouldn't be having this discussion after so many years.

I personally picked emacs for a number of reasons, you seem to already be familiar with Vim so that might be best for you.

Print out the cheat sheets, and get to work. It's terribly frustrating at first, but you'll be off the sheets in no time. After a month of steady emacs use I could not go back to anything else. I have to use Eclipse at work from time to time and I find the experience maddening; having to use keys like Page Up, Page Down, Home, etc. Emacs lets me do all that and more without ever leaving the home row. I'm sure Vim is the same way.

Pick one, learn it, love it... just don't become a zealot :)
