It's an opinion thing, not power scaling thing, and Sanji is strong as he is today.
But being a fan that was a bitter pill to swallow for me personally.
Sanji had suffered a lot that arc, and previously had beated Luffy himself so then when the moment came upon Sanji to save Luffy, it was built up to be his hype moment. But upon kicking one fodder he was sent flying to the ground and immediately cornered by BMPs.
Zoro is never treated that way, even if he has to carry Luffy through Kaidou/BM attacks. Gaban recently also had hype of saving Roger singlehandedly. Sanji failed in my eyes at that moment, and it was written in a way that his brothers paid him back by making the path for/saving them.
I think you're overlooking this quite a lot, Sanji has been put through worse..
The point there was
- Hype up the Raid Suit as something Sanji could take benefit in battles (even if posteriorly he refuses to use it to fight in actual serious battles, which is an W to what he stands for)
- Show that Sanji's kindness always moves people, even villains that seem to have no room for that.
Sanji is very rational for 99% of the time, his goal there was to save Luffy, even when he got completely surrounded he didn’t act completely desperate like he didn’t had a chance, he just stated that it had become tougher. Sanji wouldn't sacrifice him and his captain's escape attempt out of ego by not accepting assistance from his siblings, and he still behaved like he didn’t need them AT ALL. Obviously, his siblings gonna find a way to despise him even in situations whete they are supposedly helping him and his crew, but that is 100% expected, thats what we see the whole arc, his siblings were borned inclined to be like this because of Judge.
It's quite sad when you think about it because his silbings didn't choose to have Judge as their father, initially they were Judge's victims, not even Reiju can have legit good feelings, except in a very few moments where Sanji is involved. That moment was a glimpse of what his family could be, they even cheer up for Sanji, even in a weird way.
And besides, Sanji already had showed superiority to them in many different scenes throughout the arc
Saying that wouldn't happen to Zoro when i just gave you an example during Onigashima is kinda silly. You might say that wouldn't happen to Zoro due to other reasons, such as like being placed in complex scenarios alongside characters that had great influence in his childhood (even if thats mostly negative influence)
I could go further here to argue that Sanji carrying mummy Zoro is way more "humilliating" than this, blud was saying he would slice Kaido into pieces in front of Sanji's opponent lol. Sanji lowkey saved his life because he would be killed by fodder dawg, he couldn’t move at all. Then he fights both King and Queen in the perfomance floor and keeps fighting until the mink medicine takes effect.
In the rooftop, Zoro only had room to attack when he wasn't carrying Luffy, but when carrying Luffy all he could do is run (while having 3 other Supernovas to back him up, which is huge).
