All techniques counter! Using Konoha Jutsu Body replacement, Groundhog technique.
Prime Hiruzen can completely negate all ninjutsu while Old could only do it once fully(due to old age) which explains why Hashirama and Tobirama still emerged from the coffin using Technique Neutralizer.

Unbreakable defence which even Mouton could not get passed! Bijju Bombs and high scaled techniques could not get through since Adamantine is unable to be broken.
I was going to argue against this but after rereading about Hiruzen I agree. He was trained by both Hashirama and Tobirama, said to be the strongest Hokage the village had, even at his old age he was said to be the strongest of the 5 kages at the time and he's the oldest and longest reigning kage. Makes you wonder why didn't Kabuto make Hiruzen's edo "Special" as he did Madara so we can see Prime Hiruzen.
Very funny. Now stop giving him feats based on hype. Hype is BS.
Also, the "Unbreakable defence" is weak to throwing kunai through the holes. And he cant use substitution because he's kinda locked in an unbreakable cage.
