Damn, this is a tough choice. Both of them are hot brunettes with great asses. I think Jayden has better tits than Rachel, but on the other hand Rachel is willing to do anal (something I've never seen Jayden do).
Eh, I think I'm gonna go with Jayden on this one. In terms of physical appearance it's too close to call, but Jayden seems to have a more fun-loving personality based on interviews.
