I use emacs in a work environment that is primarily Vim and where we end up logging in to a lot of machines to do development on, and the two things that turn heads in my emacs setups are my fluent and flexible use of multiple windows and frames, and the fact that I'm always using my local emacs and I use Tramp to remote in to the machines, so I don't have to screw around with .vimrc files on half-a-dozen machines. Both are stock emacs.
