One of the things about emacs is its on almost every machine you can find accessible by terminal. Except when its not, which is why I know enough vi commands to do really simple things. (vi seems to be on every *nix machine without fail).

I'll fully admit that the configuration and lisp scripts are confusing in emacs. Its almost too configurable. But they are amazingly powerful. Plus emacs has the indispensable (M-x tetris)...

I've looked at Sublime, its a beautiful editor though. It seems to have some good tricks up its sleave as well
