For me it's Pele hands down. Although he did not have the flare of the more recent soccer players, he was and still is considered the best player in the world (in my opinion). I mean when you think of the bycicle kick, which is the most exciting play in soccer, who comes to mind?
Also, although the question is who is a better player, Pele handled and still handles himself better off the field and is a true ambasador of football on the global sector. Although Maradona was a great player, his reputation will always be turnished by his constant drug use. He's lucky he is still alive.
