If you discount antifeats you have to discount the Vista bullshit too
BM's anti-feats don't actually make BM look weak. 90% of them are BM getting goofed, but taking no real damage. Like robin rolling her. Okay, BM isn't serious all the time, anything new?
Also, a lot of BM anti-feats happen when she was nerfed. Like Queen landing brachio bomber while BM had amnesia, or King kicking the boat while BM didn't have zeus( or seemingly even prometheus, who was never shown until onigashima).
But Mihawk getting stalled by vista, is a clear deviation from the portrayal given to Kaido and BM, where even YCs can't stall fight them. This was a special plot point that Oda himself noted.
Even after defeating a YC1, Katakuri, Luffy was still utterly incapable of even fighting Kaido or Big Mom. There are only a handful of people who can face them.
Whereas he was more than willing to fight an admiral in dressrosa. Clearly there are tiers amongst the top tier, BM and Kaido are at the top.
