I think the "Halo Effect" creeps into play whenever Cameron or one of the other All-Stars is referenced in a comparison.
While we can all (ok, mostly) agree that she is in the Top 5, the obsession with her overall beauty tends to get her mentioned in ANY "who is the best.... " conversation.
I would say that Cameron has wonderfully slender hips and legs with a perfectly firm and petite backside. If this is your idea of "sexy", then she wins. However, if you're looking for long or athletic, she's not your girl.
If anyone has seen Cristina @ BP, that girl has awesome athletic and toned legs, without being overmuscled or unfeminine. Stacy @ HFH has long legs that go for miles.
(BTW, I vote for Cameron because in this case she deserves it!)
