This is the fair assessment unlike those that is purely sasuke bias.
Plus tsukuyomi is not something you can just go nuts with from the get-go... especially not against the kages...
So not right to make quick assessment and be fair to edo madara... He just like sasuke may have both amaterasu and tsukuyomi.
