Aerosmith gets my vote. GOT is faster as there is very little on the game that interacts with the ball and that isn't a good thing in my opinion. Also the artwork doesn't represent anything from the show, it could be used for a generic castle / knights game.
GOT Pro

AS Pro is easily the better value in my opinion.
