I have seen Ms Xena, albeit not for over 6 years.
My sessions with Ms Xena were generally very good, however for me Claudia is amongst the very best I have seen. Admittedly that is likely a chemistry thing as much as anything else. My type of session, Claudia seems to genuinely enjoy.
Ms Xena is definitely sensual, but my sessions with Claudia were more sensual and she comes across as more naturally sensual.
Ms Xena is obviously bigger and is genuinely massive, even bigger than her pictures (I once ended up seeing her on the same day as Nicole P and I was shocked when I saw Ma Xena, how big she was compared to Nicole), but Claudia is still extremely muscular and is better in terms of conditioning. I saw her today and although she is not in contest shape she is absolutely rock hard all over and ripped.
I am not into domination sessions, so it is hard to comment on who is more dominant. I believe they can both do domination sessions, from their personalities I would say Ms Xena is likely more naturally dominant, but I have not done that kind of session with her.
