I just find Vim so much faster. There is a learning curve (http://www.thejach.com/imgs/vim_learning.jpg), but once you're over that curve, you can't stand regular text-editors anymore! Fewer key-presses and your hands not needing to leave the keyboard (or at least, infrequently) = fast.

I should add, I don't just use Vim, I use the IdeaVIM plugin for PHPStorm and Webstorm, for development zen. :-)
