One thing for sure is that Zoro's physical strength, AP and endurance are now closer to Luffy , if not already equal/superior.
Luffy isn't equal to any SN on that roof! Nor inferior!
As much as I like Kidd, Luffy is above him because of FS and Ryuo!
- When you're from the same generation, you're judged based on CoC then Haki or Stats!
- Or just Bounties if both lack CoCs/Advanced haki.
If one has CoC and the other doesn't, automatically CoC user> non CoC user like with Luffy and Law.
If both have CoC then it comes down to who has better haki/stats/career like how Doffy and Hancock are compared, Luffy and kata were...
By default Luffy/Kidd>any SN because of CoC. And Luffy > Kidd because of his stats especially
FS (which only a few among the Mightiest can have, Ryuo wasn't even hyped like this)
Conclusions so far:
Luffy > Kidd > Law >= Zoro >~ Killer
Luffy : CoC, FS and AdcOa. Occupying Kaido by himself. Compared to Great Ones and Determination praised by Kaido.
Kidd : CoC. Handled Linlin with Law.
Law : handled Linlin with Kidd
*SNs trio are called Monsters by kaido*
Zoro : Ryuo. Paired with Killer to handle Homies
Killer : paired with Zoro twice now.
