Oars isn't kaido. The forces in presence are not the same here, the straw hats are not the same as back then.
Different time, different story, different outcome.

Tougher, cannot be harmed by many.
Regeneration of awakened Zoan, Queen recovered in minutes from BM beating.
Can actually harm Luffy unlike Oars.
Unparalleled physical strength.
The only points Oars had is size(paired with speed, he wasnt an easy target like Dragon form Kaido) and zombification which allowed him to ignore any damage until the point the body structure was falling apart. Then there is Luffy whose G4 has a time limit and with new Haki blasting technique he is spending more Haki than ever. How do you expect him to beat Kaido in 1vs1, lol?
You really want me to believe that Orochi is strong? Even in his hybrid form, he's still a coward who shit his pants and can't even block/dodge a slash from nerfed Zoro. Would it be Orochi like in that Luffy vs Kaido/Zoro vs Shogun Fan-Made, i would agree with you.
