I find SublimeText (and TM to a much lesser degree) have certain features that really help with efficiency, like multi-line editing and good key shortcuts for in-file search and replace and regexp replace.
Vim is like this but without having to take your hands off the keyboard, so you get a little extra. But using the mouse and having a very visual hand-eye-coordinated text editing representation is really intuitive, so it's definitely a tradeoff.
Vim takes a long time to get used to, is not intuitive, and gives an extra boost in speed by its very nature; pretty much comes down to that.
Sort of like a car: it takes a long time and investment to learn how to drive and get used to the completely new world of streets and driving rules, but once you're there you can get places way faster.
All that said, I still use SublimeText, because I don't necessarily need Vim to program efficiently (I admit, my main obstacle is my mind, not my editing speed), and the experience of SublimeText is very efficient and matches my intuitive mental model of text. So the moral is, use what works for you.
