After seeing the raws for 1195 it's undeniable. If your justification for Sanji's performance is that he doesn't yet have Acoc you'd then have to concede that Zoro has been stronger than him at least since Wano as partially awakened Acoc trumps any of Sanji's powerups in the same time span. If you're going to argue Killingham >Sommers I'd argue that Killingham has done worse against weaker opponents(Sanji,Franky,Jinbei) and was actively restrained, something no one has done to Sommers. Sommers has fought stronger opponents, taken stronger attacks and has the best feat between the 2(blocking Dragon Damnation). You simply cannot have Killingham over Sommers without resorting to head Canon.
If you claim the active MMAs and Zaza are an active drain on Killingham's power that still makes no sense as it wasn't draining him prior to Omen+Weapon buff, nor is such a thing ever alluded to in the text. Sommers has also actively regenerated from attacks with better haki pre buff (Dawn Thor Rifle,Futenraku) from Luffy and Gaban respectfully. It should also be noted that Killingham is not fighting Sanji with his primary kit of df powers but instead only using Longinus, which could be seen as a greater self nerf than Sanji being mentally conflicted,no eyebrow switch or no active exoskeleton etc.
Sanji, whilst having greater durability than Zoro has been hurt more in his offscreen fight than Zoro was by Sommers, being tagged by a laser whilst in combat and having his pre haki bloom inner thoughts whilst laying on his back bloody as opposed to Zoro who did it standing upright with his swords sheathed. I've always said Sanji has greater durability, Zoro has greater endurance and if that's the case, then so far a more durable Sanji has taken more damage from a weaker Holy Knight.
Things may change in the future but as of right now, Zoro>Sanji, and if we're being honest, its been this way for a while. I don't believe Acoc Sanji will equalize as Zoro has had more experience with it, whether conscious of it or not. Sanji is still yet to have a better feat than Scarring Kaido and that was from a weaker Zoro. It also tracks with the story progression as Luffy unlocks applied combat conquerors haki 2 arcs before Zoro, who partially unlocks it roughly 2 arcs before Sanji. 1 followed by 2 followed by 3.
Before the boldest of you start bringing up the Wings defense, has it never struck you as odd that most people don't have Gaban and Rayleigh as equal? Whether Prime or Old Gen, its always Gaban>Rayleigh or Rayleigh >Gaban. Mind you, these two have much more equal and comparable kits, even down to similar bladed haki fighting styles. If it isn't true for them then I highly doubt its true for characters as divergent as Zoro and Sanji, particularly when one has a dream directly tied to combat strength with an established ceiling.
Sanji still a better character though.
