I'd love to know too! I use Emacs for everything except C++, because I've never found anything that works as well for code navigation and completion as visual assist. (Setup time is a factor, I admit. I'm not saying visual assist isn't a bit ropey in places.)

(As a text editor Visual Studio isn't great but it's perfectly adequate and I generally get by by copying and pasting to and from Emacs if I need to do anything complicated.)
