Physically it was Anna, Pam was all makeup. Anna was a good looking chick without makeup. And jump to stardom after the Guess commercials. Pam didn't even win Playmate of the Year. Renee Tenision did, and she had natural D's. Pam went and got some implants, put on a ton of make up and then all of a sudden she is now "hot"'.
Anna had a better ass, legs and had descent breasts before the implants. Pam has a flat ass. Also after Anna had her child, she actually looked good, whereas if you've ever seen pic s of Pa without make-up, she really looks her age.
Pam was not on ( that we know of) drugs, and didn't sound like she higher than a NASA space flight.
I'd say there should be a Playmate pic duel to see who was the better.
