Page one was never temporarily knocked out at all. He was knocked down and said his jaw almost dislocated but he was never out like ulti.
Sanji knocked page one down multiply times with and without the raid suit.
I think your just being extra hard on sanji and don't wnat to apply the same logic to luffy.
I believe Luffy knocked out P1 because after he hit him we don't see him again until the next chapter. If he wasn't knocked out he should have attacked Luffy while he was fighting his sister or after Yamato showed up.
Sanji surprised attacked P1, without the RS, and knocked him to the ground while he was eating and talking to the citizens of Wano. The rest of the battle Sanji was using his RS. He did knock P1 down again but P1 also overpowered one of Sanji's kicks and forced him through several buildings. The last attack from Sanji was the last attack of the fight.
Luffy is clearly stronger than Sanji. He should be YC1+ minimal. That puts Luffy several levels above P1. The stronger you are the less power you need against weaker opponents. We can't say that gap exist between Sanji and P1. Do I think Sanji is stronger than P1, yes. The question how far does he have to push himself to deal with P1 durability and recovery powers.
