I think the sexiness is the key difference between them. I think Christy's one of the most beautiful women ever, I've got tremendous respect for her and for the taste of her fans, but she never had the same visceral impact on me that Cindy did, and I don't collect her pics fanatically the way I do Cindy's. A lot of women I know just love her, though. Here's Christy herself on the subject: ""Because I'm not very glamorous it didn't feel true to me. ... Plus, having to wear all that make-up - what a waste! Cindy was much more that kind of persona; I don't think the 'sexy girl' thing is my image at all - I get more attention from females."
