The one aspect in particular about VS that I love over all the other IDEs is the type-ahead. It's amazing. It's quicker than me (which isn't saying much I guess) whereas type-ahead in all Eclipse-based IDEs I've used is constantly trying to keep if with you. Often it just can't keep up. In Domino Designer I actually find type-ahead to slow me down as I wait for the spinny circle to keep up what I'm typing. It gets in the way of coding and slows me down! On the other hand VS's type-ahead actually helps me code faster.
