Well, in emacs you can try out evil-mode, which will get you the basic vim commands. I flip back and forth between the two: the vim commands are great when I'm focused on a single document, usually a hunk of code, and just have to make some something happen. On the other hand, if I'm flipping between editing a latex write-up, recording progress in org-mode, moving files around in dired, flipping between two different interpreters and several shells, the web browser, database query front-end, etc., then I start to get annoyed by the modes and prefer the flow I can get by not having to worry about editor state.
Right now I'm mostly using modeless interactions, but every now and then it feels good to get the vim muscles moving.
Larry Tesler would cry if he knew of this strange vim-obsession that has been creeping up all over the interwebz.
I use Emacs and IntelliJ, both modeless editors, and I've never understood the obsession with vim, but I'll be happy if someone could enlighten me.
