The problem with that logic is that the best tools also tend to be the ones that take a bit of effort to become comfortable with. If you always go with what you're already familiar with, you'll never get anywhere.

Also, it's pretty hard to judge how suitable a tool as versatile as Emacs is to your task without already being at least familiar with it.

Ultimately, I'm a big fan of trying to use new stuff "just because". I've found some of my favorite tools this way: Haskell, Emacs and even Linux.
