Wow... I had no idea that people underestimate Scabbards so much, wow... I can't believe this.
Asura Doji a solid YC1
He was the second strongest samurai after Oden which means a lot,
he was also the only one who give Oden at least some kind challenge in their fight...
And dispite the fact that he last he was still able to give Oden some kind of damage.
In a war against Kaido dispite being vastly outnumbered Asura Doji managed to go teo to teo with King and Just like his captain King used derty tricks to defeat Asura, in fair fight I'm pretty sure Asura would take down king just like Oden would have killed Kaido.
He managed to survive in Wano for 20 years and when he had his chance against Jack he showed him his place.
Denjiro a solid YC2
Denjiro and Asura Doji fought against Kaido and survived.
Denjiro was playing with enraged Zoro as he was some kind of joke and we know that Zoro is strong, ask Zoro fan boys they'll tell you.
Nekomamushi and Inuarashi are solid YC3
Even though they fought against Jack separately for some days it still doesn't take away from the fact that they were equally matching Jack and just like his captain Jack used derty tricks to win, again... (man so much dirty tricks, I think in fair fight the beast pirates have zero chance against the clamatiais) they also physically overpowered a giant Fishman who is an ancient Zoan user, which is quite impressive to say the least.
Inuarashi was also able to go teo to teo with Asura for some time and add to this sulong.
Unfortunately we don't have much feats from the rest of the scabbards but the simple fact that Luffy called Okiku "super duper strong" means that she's also YC level, btw she also low diffed Kanjiro.
Overall I think scabbards are stronger then any Yonko crew, and even in terms of falowers Oda comperes Oden to likes of Roger and Whitbeard.
