I think jena beats her hands down but and the big BUT is Briana Banks loves anal sex and dp's witch gives her the real edge. Your not a complete Pornstar if you don't love a man's shaft up your nice sphynxer. Doing some anal scenes from now on would definitly put Jena jameson over the top.
Briana because:
-she eats and swallows cum
-likes to be fucked in the ass
-likes to be dped
-likes to be throatfucked when one grabs her strongly by the hairs
Jenna is a softie as compared to Briana and always was.
