The Dukes had 12 hours of rest each while Jack none, and didnt even use his hybrid form. Wanda said Jack was a true monster. Also, Jack's bruises never came back despite all those panels.
It's clearly more impressive for Jack.

Explain why Jack couldn't defeat Inu/Neko their first 12 hours or any time afterwards if he truly could have? You say he didn't use hybrid but there's no proof of that but even if he didn't that doesn't take away from the fact that the dukes are YC3 level. YC3 aren't all equal, it's just a general range of power, so Jack being slightly above them doesn't matter.
