My two cents on stats, since other dimensions used in this thread to compare like individual trophies by voting don't make any sense IMHO:
-The WC is the most important competition football-wise, even more during the 50s-60s. Well, Pelé is the only to have won 3 of them. At the same time, he scored 12 goals in 14 matches over 4 tournaments, a 0.86 average. Only Ronaldo Nazario is close with 0.79 over 3 tournaments (we could consider Fontaine and Müller above them, but they only played 1 and 2 WC respectively), but he only won 1 WC while playing. No modern player is even close.
-Considering international football, the Southamerican championship (currently Copa América) is the equivalent of the European Cup for brazilians therefore would come next on the list. Unluckily, the south american federations management at the time was chaotic so the tournament wasn't constantly played and most of the time Brazil used regional squads and/or reserves. But the one time Pelé played, he scored 8 goals in 6 matches (1.33 average) and was the goal scorer and player of the tournament. At 18 years old.
-Since Pelé didn't play in Europe, it's difficult to compare regarding club competitions. But we do have the results at the Intercontinental Cup, which was quite important at the moment. There, Pelé won the only 2 tournaments in which he took part, and he played 3 matches scoring 7 goals against the champions of Europe. That's 2.33 on average facing the best teams of the world.
-One could say that only 3 matches aren't enough to establish predominance club wise (even when he missed another 2 due to a foul by Trapattoni in his last one). Then we would have to resort to regional club competitions, at a time when Copa Libertadores (SA Champions League) was just starting. There, Pelé won the first two competitions in which he took part (1962 and 1963). In the first one, due to his injury from WC 1962, he only got to play 2 matches. Well, he scored 4 goals. The second one was the final, where he scored two. The next year, he played only 4 matches (the defending champion went straight to semifinals) and scored 5 goals. He didn't play in 1964 and Santos lost. He returned in 1965 and scored 8 in 7 games, being the goalscorer of the tournament. Bottomline, 2 titles in 3 editions, with 17 goals in 13 matches for a 1.31 average.
So in the end, considering only A matches of A tournaments in clubs and NT, Pelé:
-Won 7 out of 10 tournaments (only lost 1 WC, 1 SA and 1 Libertadores)
-Scored 44 goals in 36 games (1.22 goals average per match).
One could say that's not a lot of top matches in order to form an opinion, but A) there weren't more official tournaments available at the time and B) between 1966 and 1971 most of the non domestic matches that he played were exhibition tournaments, making those stats difficult to ponder.
