Enma Staff strength seems to be quite underrated in the series. Basing it off of manga feats it is much more powerful than many people want to accept. I also believe Enma's strength may be dependent on Hiruzen's strength as well but here are some examples
Examples:
Pushing 100% Kurama out of the village
Kurama after Kushina held him for Minato to seal
Clearly the brute size of Kurama was drastically cut including his overall strength.
Now lets analyze 50% Kurama
Tanking Senjutsu Giant Rasengan effortlessly at 50% Kurama
Matching Perfect Susanoo in strength and doesn't move at all (50% Kurama)
With this being said how can people doubt the sheer strength of Hiruzen and Enma staff especially when we saw what he could do 12 years younger against a full powered Kurama
