But do remember, Hiruzen did master all 5 Nature Transformations, and knows most of the jutsus in Konoha, I think. Plus, he was shown only in his old state, so we wouldn't know what his full potential would be when he's younger. But yeah, I still don't think he would be stronger than Hashi, but he does have the potential to be close to it.
