The only reason I don't use ST2 is because it isn't nearly as good as Vim at indenting and highlighting the languages I use. Another reason would be that I can't use it in a terminal and would have to switch to another editor.

But the rest of ST2 is utterly fantastic. In particular, using Python as the extension language. Elisp is okay, but VimL is terrible. ST2 is the only popular editor I'm aware of that has a real programming language as its extension language and not a editor-specific language.
