Customization is way easier than in Emacs, you just unzip an archive in your .vim dir and (99% of the time) it works. I have plugins that do everything I've seen in Emacs that has to do with code, and then some.
Vim is no more the tiny start-quick-edit-close editor that it used to be.
Edit: I don't want to start a holy war here. Emacs is great, and I in fact have it opened right now. It's just that it's supposed to be able to do amazing stuff that Vim can't, I'm saying that that's probably still true, but to a way lesser level than before.
