the best way to exit Vim (according to an Emacs user)

What an obvious lie, vim absolutely can support WASD, that's just a tiny configuration away.

nnoremap s j
nnoremap w k 
nnoremap a h 
nnoremap d l

The rest is entirely true though

@Bankenstein as Emacs user and former vim user, I can confirm this is the best plug-in for vim
