Hiruzen in his prime is stated to be someone who knows and can use all Konohagakure's jutsu. And it's not just in the early stages of the Manga where that is stated but the 4th databook as well. The databook even announces that Hiruzen had talent that surpassed Tobirama in just his childhood. It's sad we never got to see how powerful he really was since he was still reanimated in his old age, but Kishimoto made it clear. Hiruzen in his prime is someone that just sounds godly.

I don't see how even Hashirama (even with his almost endless reserves) can compete with someone who supposedly can use Flying Raijin, the Hidens, Spirit Transformation, and every other technique that comes from Konoha unless he stalls until Hiruzen runs dry. Then we also know Hiruzen has all knowledge of every jutsu from Konoha as well, including Hashirama's. Since there hasn't been a showing from him in his prime, we can only go by what Kishimoto himself says.
