This shit has been discussed a gazillion times in these forums. The simple answer is that Hashirama is the strongest Hokage after Narutard, and the whole thing with Hiruzen being the strongest has been retconned. Hiruzen may be just below Hashirama and slightly over Tobirama, but he's no longer the strongest Hokage. Initially, Kishi didn't intend Hashirama to be the strongest Hokage. Then he changed his mind as the story progressed because he was making shit up as the story progressed to a certain extent. And the end result was that the Hiruzen shit got retconned.
