I'm one of those guys. Using Aquamacs.
It's deeper-blue theme shipped with GNU Emacs.
On different machines I have different sets of packages installed, but my must-haves are evil for vim keybindings, magit, best GIT GUI ever, and ag to use with the_silver_searcher, the best program for searching text in source code.
My config file: github.com/tail-call/.emacs.d/blob...
I use space-prefixed keybindings like in Spacemacs, and they're really fun to use and easy to remember, so if you're emacs+evil user, consider setting up some, too.
