I was not at all a fan of the 2.x version... and I've been a pretty hard core emacs fun for awhile now... but I'm currently evaluating 3.5.2 and I'm more or less liking it. In other word's, I'm really annoyed at certain things I can't do that I could do, but otherwise I really like it... and as my projects are getting significantly more complex these days it's really helping.
