Watching a lot of both, albeit on tape...
I think Eusabio from same era was better than Pele. Far more explosive and scored goals at a better rate at arguably a better level of football.
A lot of Brazilians would say Pele is only ~2nd-3rd best Brazilian ever, he gets more praise in Europe than South America. Garrincha is probably the #1 in Brazil, and Jairzinho in similar level to Pele from what I understand.
I think:
Messi, Ronaldo, Pele, Eusabio, Garrincha, Beckenbaeur, Maradona, Cruyff, Puskas... are all guys that can make "an argument" for. Albeit some stronger than others.
