Zoro and Lucci were both struggling with the seraphim even though they had back up in Kaku and Luffy respectively. Sanji was no diffing the same seraphims with his arms folded - like nothing - by himself. I guess feats do matter hey, but only when they match my agenda.
Zoro and Lucci were struggling just as much as Zoro was struggling holding two of them back alone will defending two hostages.
We got, what, two panels of Sanji showing off his exoskeleton and just starting the fight? In which he wasn't even alone.
Yeah, I can see you caring about feats for your agenda.
