Isn't Mika's design based off of an actual person/wrestler
Not the guy you quoted but if I had to hazard a guess it's because Cammy's is a lot less "girly" and fetishy, for lack of a better term. It's got all the hearts, frills, and big bushy pigtails while putting her cleavage heavily on display. And it doesn't emphasize the butt any less than Cammy. On the flip side Cammy's leotard IS ridiculously tight but it at least seems somewhat practical. She might as well be wearing a one piece swimsuit. Plus her more serious, action girl attitude sells it better.
