I think Pele and Senna are incomparable.
But Senna captured more of the hearts of Brazilians, in my opinion.
Look at what happened when Senna died [1] and compare to the national reaction now that Pele has died.
Millions have lined up on the streets to say Senna a goodbye.
Of course the circumstance (Senna's crash) has an influence, but still...
To this day, Brazilians still have a hard time holding tears when they remember the day Senna's died.
