I guess I'll go for it.
AP goes to Garou (since Chun-Ma's amp puts her at L7B).
LS also goes to Garou. Mm.
Skill? I'll give it to Chun-Ma.
Chun-Ma's Cultivation makes this a closer fight than one would think. Chun is gonna be decking Garou and Garou would adapt to said styles. However, somehow Chun-Ma can replicate Garou's RASRF and make a better version of it, in which I don't think Garou has ever seen before. Yeah sure, he can do the style by himself (RASRF normally requires 2 people), but he has never made a better version of said style. Along with the other 2 styles that Garou has that will also be replicated, they're both gonna be decking each other's shit in to the end of them.
However... one problem that this version of Chun-Ma has. Survivability. Low regen and no immortality whatsoever. Yeah that's messed up. Chun-Ma would get messed up the moment a good hit connects and Garou would survive a good chunk of hits thrown at him.
With that said, I'll go with Garou, mid diff. Chun-Ma has the copy styles but not the survivability.
