Both obviously have very similar playing styles.
I disagree. RG3 has excellent accuracy. He can hit a downfield receiver in stride, and before Garcon got hurt, you saw WAS trying to run plays like this. Vick, not so much. He's great at buying time for his receivers to get open, but he's not good at throwing into tight coverage. Thus Vick's value is far more dependent on the health of his WRs than is RG3.More importantly, though, RG3 gets designed runs, while Vick doesn't. When Vick runs the ball, it's usually because something went wrong with the play. With RG3, a QB draw is often the first option. So I think there's a fairly significant difference in style between the two. And for fantasy purposes, I'm more bullish on RG3 than Vick.
