Best isn't mentioned in the same breath, but he's mentioned.
You don't think it's entirely possible Pele could have played his hand in making sure Garrincha was forgotten? I'm not trying to play HBA here and conduct a conspiracy, but it would fit Pele's antics.
I don't know to what degree has Pele elevated himself above his team mate Garrincha, but it is not impossible. But I think it had to do more with FIFA than Pele, the latter just took full advantage and if FIFA was a person, he/she would be like WTF??
To FIFA's credit though, you'd think they would actually elevate someone with a drug problem? I mean fun and religion aside, alcohol and coke are not things you promote, and nor should you as a sports institution and Pele was a good boy also insanely talented and decorated so it makes all sense. Maradona's name would have been wiped had he been in an older generation but there were colored tv in every corner at the time and he promoted himself as well so they couldn't shut him up or hide him.
They even split the player of the century between him and Pele.
