You should look into Viper. And if Emacs doesn't start quickly enough for you, you should run it as "emacs --daemon" and then "start your editor" with emacsclient -t (or emacsclient -c, if you want an X window).
Once you've gone the Way Of The Emacs, there is no reason to use vim... unless you have some internal application written in vimscript, of course.
