If he had it he wouldn't have died in chains.
There is no proof Oden had it. The scabbards using barrier ryuo were said to be using Oden's ryuo.
Vergo>=Pica, Vergo was the one Doflamingo respected the most. You want to claim they are equal by crew hierarchy but refuse to accept Sanji as Luffy's 3rd in command monster trio member despite all the evidence throughout the years. your bias is showing.
Sanji achieved his goal of saving the marines and exposing Vergo while in a nerfed state from the explosion, Vergo BTFO'd Smoker who had been Luffy's superior rival until that arc and was used as a Law hypetool.
Zoro highlight of the arc was getting BTFO'd by the yeti cool brothers.
Maybe he had seastone chains Roger also died in chains
Then explain why Kaido compares Luffy with internal damage to Oden ?
Even if we go your logic >= Zoro still easily owned Pica well Vergo wasnt even go all out against Sanji though Sanji may have a handicap Vergo held back he didnt even use the bamboo stick
Picas golem form>Vergo anyway
So Zoro is far stronger than Sanji
Law easily owned Smoker without sweating lol Sanji also got gased in the ship and was captured by fodders at least it was no names who got Zoro
Sanji was 3rd Jinbe joined now Jinbe is 3rd when Yamato joins them like Oden did join Roger then Sanji falls to 5th pre ts yes Sanji was Zoros equal close to him but now the gap is too big
One got teached by the world strongest swordman the other one by a okama thats the difference
Sanji is nothing
