No he's is not, Doffy got completely outclassed by G4 Luffy
Cracker was sent to deal with Luffy knowing full well Luffy defeated Doffy
Kaido thinks Doffy is weakling while he holds a much higher standard to Law
Law got stronger after dr it's standard shounen power creep and we already know the strawhats get stronger after each island the same is for Law
katakuri is similarly outclassed by g4 boundman
so is cracker
katakuri had his fs to evade it
and cracker had his biscuits as meatshields
you have to recognize doflamingo in the same vein had his awakening to run luffy out in similar fashion, doing all this while suffering the effects of gamma knife. it took the strongest attack we have seen from luffy in g4 combined with law's earlier efforts of killing him to completely shot him down. the moment cracker stopped hiding behind his biscuits similar to pica in the zoro fight, he was exposed.
"Law got stronger after dr it's standard shounen power creep and we already know the strawhats get stronger after each island the same is for Law"
i find this explanation insufficient
while they get stronger from island to island acc to zoro
the difference shouldnt be as large as you make it seem
just cause he can harm kaido with an injection shot( internal attack)
doesnt mean the same attack in dr wouldnt have done close to the same.
again he is much stronger now due to his awakening not due to a power creep.
