The thing is, I would argue he has better footsies in the neutral, that b1 and F2 are great.
And in the corner if he's staggering things into laser it's really difficult to stop him, you can only just punish regular laser if he's too close with b2 catdash, which if you don't get the punish (and it's tight) is a full combo punish.
Might be a 5-5, but it seems slightly in his favour, even Sonic put up a status saying Manta "regulates/normalises" CatWoman, which I would assume mean he beats her or at least does very well
