While I agree with you that Spencer and Vance are similar in some areas, there are also some very big differences. Both are extremely hard workers who can go for an entire game. While I think Vance is stronger in the air (enter Spencer's height here) I think Spencer is better with the ball at his feet. I have not seen a ball that Spencer can't play and he controls the pace of the middle so well. Now I know Spencer has been playing college ball for two years and that some say it's ridiculous to compare the two for that simple fact, but this is how I compare the two based on high school performances. I think Vance is a little more rough around the edges as far as skill is concerned compared to Spencer but maybe after a couple of years he will be able to fill in nicely for Spence.
