I'm not forgetting the sneak attack done from behind Obito when Obito also thought he was invincible.

FTG plus Sage Mode is powerful, but they only managed that because Obito underestimated their ability to harm him and Tobirama had a mark on him he didn't realize. After that, Tobirama noted a sneak attack like that again would be impossible
