"YC1" is a fan made term; King and Queen were practically equal, as made clear by their bounties, which is the objective value that Oda gave them to express their level of power with precision. And Sanji beat Queen faster and with less difficulty than Zoro beat King, even though Zoro had just eaten a miraculous Mink medicine, while Sanji had just been beaten up by Black Maria and had to fight King and Queen alone at the same time before Zoro arose to join the fight.
Douriki only measured their strength without taking into consideration their devil fruit powers;
Since Jabura had a carnivorous zoan for at least 5 years, while Kaku was still struggling to learn how to use properly the herbivorous zoan devil fruit he had just eaten, it's obvious that Jabura was much stronger than Kaku
And Sanji beat Jabura faster than Zoro beat Kaku, even though Sanji had just been terribly injured by Kalifa, as pointed out by Chopper.
Therefore:
Sanji >> Zoro
