After seeing Hashirama's prowess, it's kinda hard to believe he isn't the strongest Kage to have ever lived. Hiruzen may have mastered all five basic natures, all of the jutsu in Konoha (except for kekkei genkai and hiden techniques obviously), but these feats are nowhere near the level of Hashirama's, who could take on Madara Uchiha and the full Kurama at the same time using Sage Mode only to take the Nine-Tails out of the game.
