tobi has to be izuna(madara's brother)
he's old, visably aged
he has had BOTH his eyes removed, but he uses other sharingan user's eyes
i believe he was using the name madara, because it was a threat at one time, izuna was more of a folklore
honestly yeah hes the next best choice, it could also be shisui, the best genjutsu ninja the the anime isn't the best for nothing
