However, Evil mode now works pretty amazingly right now if you like Vim. I use Emacs with Evil and Vim practically interchangeably. My biggest frustration is a bug (which is probably unfixable) with how undo doesn't always correspond with a vi command. There are some details with how buffers are specified, etc, but you can customise it to get close.
Spacemacs is a pre-setup Vim setup for Emacs using Evil mode which is highly recommended, though I haven't used it (I like minimal setups). I don't know if anyone has ever setup edit-mode key bindings for Org mode, but I just use the Emacs ones (I was originally an Emacs user before switching to Vim... and then back to Emacs :-P )
