Let it go bro, Queen isn't it. Dude was a bum.
You would be better off arguing that by EoS, Sanji will be close to Zoro in power, due to Rayleigh/Gaban comparison.
King and Queen had some rivalry, yes.
But Oda made it clear by the end of the arc that King was levels above him. Queen has zero arguments to place him above rooftop Zoro, while King ragrolled rooftop Zoro. Queen, when King wasn't there to listen (he would never hype up King in his presense lol), hyped up King as a God that Zoro was hopeless facing against.
There were even some Kaido/King parallels. Kaido choosing him as his RHM/first mate, calling him strong enough to be worthy of name "King", both having similar ultimate attacks (dragon with magma esque flames, obviously Kaido's bigger and stronger), both having flashbacks of each other when they lost, etc.
King has every single stat above Queen, whether it's attack power, AOE, speed, CQC or durability. King's durability completely shits on Queen (the one thing Queen is good at)
Current Sanji would mid-high diff Queen.
While depending on if King's flame on mode is retconned to invulnerability instead of giga durability, King has a shot to be above even current Zoro. And even otherwise (if advanced conqueror's can damage flame on mode), King would push current Zoro to a high diff.
There is only so much that side by side scaling can leech, when there is so much more context and feats aside from it.
