Regarding acme, everyone comes in and goes "Yuck, you mean I can't type 'C-c M-x undoify'?" However, once you get used to it, it's actually rather nice. I have something like 30-40 files open in acme right now, and I find it far, far easier to manage open buffers than in Emacs. Arranging and re-arranging buffers (to use the emacs term, since it's familiar) is very convenient and helps me keep things organized.
It also has "mouse shortcuts" (chords) that tend to reward using the mouse more--meaning you don't need to switch from mouse to keyboard as often, because you can do cut, copy, paste, search, command execution, etc. all with a click of the mouse (and no hunting through menus, either).
It's hard to explain... you really have to use Acme, or even better, watch someone use it. http://www.youtube.com/watch?v=dopu3ZtdCsg seems to be a decent intro, although I haven't had time to watch the whole thing yet.
Much simpler and quicker than stretching your arm to the mouse, futzing around with the cursor to find god knows what menu option, clicking on it, and moving your hand back to the keyboard.
Having 30-40 files open in an editor is not impressive either. You can easily have hundreds of files open in vim, and navigate between them without a problem.
The mouse chords might make the mouse more functional, but it's certainly a far cry from having over 100 keys and thousands of key combinations at your fingertips.
Not that using the mouse excludes the possibility of using the keyboard, but as a vim user I almost never have need to use the mouse -- except when I've switched to vim from another application that requires mouse use and want to paste something. After that, my hand goes right back to the keyboard, because using the keyboard is just far more efficient.
Acme's forcing mouse use on the user is one reason I am really not very interested in using it. However, I am interested in seeing if there is anything it can do that doesn't absolutely require mouse use that could be integrated in to vim.
