He hasn't shown anything better than King speed wise. In fact, he did prove how much he actually lacks in the ability to sustain mental and physical activity (stamina) while King can move at speeds where you can't even see him for as long as he wants. So again, no, sanji is not faster than King.
Wait wtf, so even after I told you that King's fire ain't even fire any longer but instead magma you are gonna keep saying that sanji's fire is better.......than magma.....Jesus Christ.
King has AdvCoA or otherwise his hakied up sword would not be able to withstand the heat that magma produces we have seen magma literally disintegrate swords just by being near them.
And oh absolutey he does have CoC (the basic one) he uses it in this chapter in a clash against Zoro's they do the CoC eye glare and everything. So cope harder please.
He showed Kong Gun level AP. That's it.
Show me something he's done that's better than Imperial Deep Pride Stake that casually destroys entire sections of the island of Onigashima or something that can compite with his mountain range size explosions or magma sword technique.
I'll wait...
So half of your arguments are headcanons?
King wasn't stated to have adv CoA
By your logic sanji has Adv coa too because his shoes don't burn from the heat
Sanji's fire turns into lighting, that's how it is
Magma can emit lighting btw
King can emit hot flammes, that's it, they aren't hot enough to emit electrical discharges
You are literally using headcanons that don't even make sense
This is just pathetic, king didn't use coc, otherwise zoro would've stated it
Sanji pre awakening covered a mountain sized Fishmen in flammes, and yes wadasumi was stated to be the size of a mountain
Sanji with weaker flammes could emit that much fire
His raw strength is even higher than kong gun
Add on top of that flammes that literally no one, not even mera mera no mi users can produce
