The main thing I like about Vim is that it "lays under the hands" better than any editor I have used. I can use Vim to do things without spending a lot of thought the actions themselves.

Despite what everyone says about learning curve, I was able to reach a point where my productivity was equivalent to other editors a few hours. Within a week, I was able to work much more quickly and smoothly than I was before. The payoff was very quick.
