Nowadays I can't really think of a good use for Emacs. I use XCode for C++, Textmate for Python (and some old PHP and Java), MacTex for writing articles...
But man I'd love to use Emacs again and whip out some Elisp!
I found that Cocoa Emacs is faster to setup and get running, but once you have Aquamacs behaving the way you want it the extra features really are worth it. For me, tab support and the ability to re-open windows & frames from the last session seals the deal.
One oddity that I struggled at first with was how to get it to load ~/.emacs.d/init.el. I eventually solved this by loading it from: ~/Library/Preferences/Aquamacs Emacs/Preferences.el
