Out of interest, what in your opinion was so bad about VS that you wanted to get rid of it?
Mostly I think it's just about preference. I like my editor lean [insert joke about emacs being bloated here], visually non-distracting and customizable. I also try to avoid using my mouse. Emacs is all of these things for me, VS is not.

That's the kind of things that really set IDE vs editor in terms of usability.
