Both of these women use submissions and high impact striking, and Gail is supposedly a "high flier" as well. I have to give submissions to Danger. I have watched a few sub exchanges featuring her and have no doubt that she could stretch the hell out of Kim.
Striking I give to Danger as well. I think Gail's strikes look best against Kong, who I think just lets her hit her as hard as she can. Danger has a good lariat and hits pretty darn stiff.
I would give the aerial offense edge to Kim. Over the last year she has mostly been able to hit her high spots. I've never seen Danger work the top rope much ( I could be totally wrong on this).
I think that Danger is probably the better worker of the two, but this is a WWE match and Kim is a former champion. With the addition of being a TNA champ, Kim's status and notoriety are probably enough to win this for her. I have seen Danger bring the house down in front of fifty people, but she doesn't draw shit on her own.
