I see your point, but I don't think comparing era's is possible because of the discrepancy in quality of things like nutrition, training methods, speed of game, rules, etc... If MJ was born 30 years earlier, there's no way to tell how great he might be, but the same principle applies to if Wilt if he was born 30 years later. I would say it would be a toss up because it's a hypothetical question, they were both so dominant during their respective times. Kind of like Wilt was the MJ of his era, and MJ was the Wilt of his era, in terms of being so accomplished in all facets of the game.
