Most of the differences I noticed revolved around automatically changing indentation levels(one of the best ways to get uninstalled) and autocompletion which sometimes didn't work(file name completion) and once it refused to autocomplete a certain string without removing the underscores first.

I'm sure a lot of this can be fixed by changing some configuration options, but I don't see a reason to change the editor just for the sake of it. Emacs is awesome in some ways, but it's not my cup of tea.
