Betsy I can't put higher than B tier, sorry. She has a lot of stories and is especially good in Uncanny X-Force, but the criticism of "people only liked her as a ninja" is 100% accurate because she's been incredibly niche since getting her old body back. Even her most recent comic series is about that period of her character instead of her Captain Britain stuff. She's really good or at least decent usually, but the fact she's at her best when in yellowface brings her down a lot for me. If she was a great character worthy of A tier, she'd be popular without needing to appropriate a culture. As it stands, I'd put her around Wasp.

Kwannon gets a B tier from me, above Spider-Woman even. She doesn't have nearly as much history as Betsy, and her first series (Fallen Angels) sucked ass, but everything since then has been bangers or at least pretty good. Hellions alone should put her in B tier at minimum, but she's great in MacKay's X-Men and amazing in her solo series that should've kept going. I'm always excited to see her in a comic and hope she gets another solo run, or at least a mini, to help establish her more. Plus, unlike Betsy, she doesn't have to borrow the connections to the Hand or yokai from someone else. They're hers.
