Technically he saved the SA only once and Naruto made it possible for minato to do so the second time...
Also while I don't care about either in regards to who wins I just wanted to counter you saying 1 rinne/sm madara wrecked tobirama and minato got wrecked by juubi kind however true that may be madara was on the opposite side of the battlefield minato and kakashi chose the weaker target it was either pick madara to face or obito controlled by black zetsu and well kakashi and minato chose black zetsu obito when we all know madara would have wrecked minato and kakashi a s well... neither can see or sense limbo no can ftg touch madara sm reflexes so you can just retract that point you tried to make as if minato would have fared any better
