It is the truth
Zoro protected 4 noobs better from stronger enemies than Sanji did from weaker enemies.
Anyway, answer this don't run away
Who performed better: DR Zoro against Fujitora in 2014 or current Sanji against mentally nerfed Kizaru in 2024?
If you are not biased you can see Zoro overpowering gravity while Sanji so called fast one never seen rivalling Kizaru's light speed.
You can see Fujitora praised Zoro's flying slash AP while you never see Kizaru praised Sanji's kick. He only got surprised because the boots blocked his laser.
So again even if we don't count Vegapunk dying, who performed better?
