Depends on how you look at it. Michelle Yeoh is subjectively prettier, more charming, and a better overall actor... but objectively, when it comes to actual martial arts, Cynthia Rothrock is second to none, she was bona fide champ in multiple disciplines from a young age. And I think watching her fights during her peak, she was better at it than nearly all the Chinese action actresses (most had dance backgrounds) in the same category as her.
