- DK wins easily.
- The sages are getting oneshotted here. The physical sage got oneshotted by Zel's Nebula and his attacks didn't do much damage to him either. The magical sage also got oneshotted by Zel. His attacks tho, were far more impressive so I'd say those can definitely hurt The One. The moment The One catches them, it's a oneshot. The Sinner didn't show any feats that made me think he would stand a chance at beating The One, so unless Escanor has the one minute time limit, he wins.
That's debatable. To me it looked like he tanked the second attack considerably better than the first one.

It looks like the first attack makes considerably more damage than the second one judging by his expression alone. He also recovered from each attack immediately and counterattacked. He's far from being fine I agree, but I don't think he's on death's door as you're implying. I agree that the constant degradation must take a toll on his durability, but we don't know by how much. It's pointless trying to argue how much more durable would he be without the punishment because we don't have anything to look at and compare.
Maybe you're right and the damage he took from Ludo's attacks was incredibly high and he could have tanked the attack had he been on good conditions, but I don't see the damage he took being that great. Even if he could tank it, it's for sure he would end up being on death's door judging by how the attack was enough to separate them again and leave them almost dead.
When it comes to swordsmanship Cusack showed better feats than Zeldris in 1st DM. However, in 2nd DM he was able to compete with Mael to some extent (even if he was holding back) and he was even able to blitz and considerably hurt him from one attack at some point. To me, that's far more impressive than what Cusack or The Sinner did show.
