No contest for me: Carmella Bing. Prettier, taller, nicer tits, nicer ass/legs/feet, smoking bikini body (especially when she more toned), and much better performer.
Austin Kincaid has a pair of the finest tits ever IMO, my jaw dropped as I watched her nipples get erect in the first scene I seen her in. They're both hot but I voted for Austin because of that scene. :thumbsup:
