Luffy was equal. When he beat Kizaru he ran out of energy, causing a tie. After they were unable to move, Kizaru recovered first and then fed Luffy, showing us he wasn't really trying.

Luffy wasn't either. He states to Kizaru when they begin battling in G5 that he almost died from the barrier and he wasn't using any Advanced Haki against Kizaru. He used it once and Kizaru was knocked down for a while. Luffy then 2v1'd Saturn & Kizaru and was overpowering them.

Still, if it was Luffy>=Kizaru, Sanji and Zoro are still losing.

Zoro & Sanji, extreme diff.

^^It wasn't though. Luffy one-shot Kizaru once he used ACoC and later overpowered Kizaru & Saturn simultaneously though to give Kizaru some credit, he was mentally nerfed but Luffy was also severely injured since he almost died from Vegapunk's barrier.

Yeah we really don't know how hard either were trying, so I'm not going to try and argue a point that I can't prove.

Zoro and Sandji negatives. There’s no character named ‘Wizaru’ (okay extreme diffs)

Kizaru is a W

Aramaki no diffed King and Queen in Udon

Zoro and Sanji extreme diffed King and Queen in Onigashima

Kizaru extreme diff Aramaki by logic

Conclusion : Borsagoat D. Wizaru win no-low diff. Other opions are biaised af. Just watch Kizaru toying with a G5 main charac

Zoro and Sanji slammed King & Queen? Also, Ryokugyu defeated WEAKENED versions of King and Queen.
