Simple Question: Who will be the better player after its all said and done?

You have Jason Heyward (Ugh I loathe him) and you have Buster Posey for SF Giants. Then you have Mike Stanton of the Florida Marlins and after that the newly signed Bryce Harper of the Washington Nationals. Last but not least, my favorite of the bunch, my boy, Domonic Brown of the Philadelphia Phillies. Who will be the best out of the bunch?
