Which players are better?

PLEASE READ: Do you think that smaller players or bigger players make better finishers in soccer/futbol. For example you got players like Lionel Messi (5'7") Franck Ribery (5'7") Giuseppe Rossi (5'8") David Villa (5'9") ect. that are all brilliant goal scorers. But on the other hand you've got players like Wayne Rooney (5'10") Christiano Ronaldo (6'1") Didier Drogba (6'2") Zlatan Imbahimovic (6'5") that are very good as well. Which do you think make better forwards?
