If Luffy,Kid,Killer,Zoro and Law put on atleast a similar type of fight the Scabbards gave to Kaido,but this time against Kaido and Big Mom with similar degree of damage implication between themselves, I guess all those five are atleast superior to any individual scabbards.
Luffy was sure to be stronger than any individual scabbard,Zoro too after the training but it will be confirmation for guys like Killer that nearly nobody was putting that strong.
These 5 Sn would be confirmed much much stronger than 9 Scabbards in the upcoming chapters.
