You are right about the defense and durability not being the same. I only would assume that Cracker has high durability given that he has a giant burn mark on the right side of his face and (is still alive and has his sight) which I would assume that he recieved from battle (possibly the only other guy to see his real form) but at that point I am speculating.
I agree that Doffy definitely was a tank in his battle against G4 luffy, but in regards to actually strength I witnessed Cracker have way more on a even battle against luffy than Doffy did. Doffy vs G4 seemed more one sided in luffy's favor. Cracker on the other hand was able to injury G4 and his multiple Biscuits armor could possibly overwhelm G4 Luffy.
In response to your point about ABC logic, I completely agree that it shouldnt be used in the one piece world but in this case there is evidence to help justify it. When Doffy used his parasite technique on Luffy, his G4 was easily able to break out and at this point Crackers armour has shown camparable haki and strength to Luffy's G4 which we could use to confirm that Cracker might also be able to break parasite with ease. Also Doffy's Strongest Attack and Defense was overcome by Luffy's KKG (which might not be Luffy's strongest attack) and we also have yet to see Cracker's Strongest attack but from portrayal it should be enough to almost rival KKG. But this is also speculation as we havent (and probably wont) seen Luffy defeat Cracker.
I personally dont think it is without reason at this point to state that Cracker is stronger than Doflamingo. Thes last 2 chapters has given us more than enought to help make and justify the claim.
Sabo also has a giant burn mark and his eye sight and he got his scar when he was a pre-teen. Cracker said he hates pain and based on his armor and his haki I'd say it's less likely he goes into a rampage when hurt and more likely he has low tolerance for pain.
We still don't really know how breaking out of Parasite works. It could be physical strength, it could have been because of the rapid change in size for Luffy, it could be(the one I think) connected to will power. Why I doubt it's physical strength based, if it is then that means DR Luffy>MF Jozu.
I have no problem with that being the case if it is, I just am not convinced 100% that's the case since Jozu still fared ok against an Admiral at MF. Why I think it's will power based is 2 things, the person we saw break out has king's haki and the strongest will in the manga; secondly Parasite seemingly infiltrates the body and let's Doffy control their actions to do whatever his will desires. It seems Parasite makes the affected disregard their will in favor of Doffy's and the only way out is to have a higher willpower than the caster(Doffy). Just my opinion on how Parasite works, if it's shown that's absolutely not possibly the case please let me know.
Also wasn't Doffy able to parasite through Jozu's diamond? Chances are as impressive as Cracker is, diamond is still stronger than his haki biscuits. Anyway what I do know is this "new" attack would have ended Doffy no problem and Cracker too if it hit, Kong Organ(Kong Gatling) is monstrous.
I agree with the clone thing doffy clones should have more advantage in outside area seeing as the clouds would provide more string and they should be able to fly/glide like doffy
But physically they should without a doubt be inferior to the crackers
I find cracker ability intresting but what I like most is that he can put his haki that strongly into his devil fruit something we've seen but none of the ppl we've seen do it (bar akainu) have done it so flawlessly
Cracker's clones are definitely stronger than Doffy's clones.
Just read the chapter and let me tell you, Cracker is undoubtedly > Doflamingo.
I don't see how anyone can have read this chapter and got Doflamingo was stronger.
Doflamingo couldn't even hurt G4, all he could do was graze his skin with awakening which did cause blood but didn't have a noticeable affect on him.
Whereas this time Cracker nearly cut off G4s haki imbued arm like butter and Luffy was in noticeable pain. And did so with some no name slash.
Everybody talking about his durability/endurance but if his CoA offense is better than Mingos then so should his defense while defending with his CoA.
He say he doesn't like pain, but that only implies if your strong enough to bypass his CoA defense.
He didn't nearly cut his arm off, and you guys talk about over hyping. He cut his arm, yes it's an impressive feat but he didn't "nearly cut his arm off" or cut "halfway through his arm" He gave him a decent cut that's it, stop trying to gas it up more than it was.
