The EMS = Perfect Susanoo fan theory stems from a flawed way of reasoning. Just because Madara and Sasuke weren't seen using it prior to obtaining EMS. Susanoo has developmental stages last time I checked, just because they polished theirs post-transplant doesn't mean the transplant had anything to do with it.
