Emacs user here, and the whole "electric-mode" stuff (for matching parens or other balanced pairs of things) I find really quite useful. And closing a pair is usually something like shift+enter, which is quite simple (but also - at least in Emacs - generally completely configurable). I think the benefits outweigh the pitfalls, personally.

Can't speak to other editors though.. I don't want to sound like I'm trolling, but they generally feel quite clunky, compared to Emacs (ducks, runs ;p )
