Only a fool would debate against statistics. If titles were the deciding factor one could argue that Eli Manning is better than his brother.
I believe what it comes down to for most people when picking "the best" is how they (feel) about the way a particular player approaches the game, his off field personality, does he have swag, and even the women he dates or marries. Personality is a big influence.
Joe Namath many years ago was considered a "rock star" quarterback and he only won one Superbowl! :)
Having said that between these two quarterbacks I'd rather watch Tom Brady. His style of play reminds me more of my favorite quarterback of all time: Joe Montana! :)
Joe doesn't hold many records at all. He was always calm during the storm and teams feared him whenever there's time left on the clock.
