You are mixing your names a bit there. Did you mean Jasper vs Edward or Jackson vs Robert? Either way though, I have to go with Jackson, he is gorgeous... and that smile makes me melt.
Do you see Jackson Rathbone on any of the Sexiest Men List like Robert?!?!?! No, I don't think so. Definetly Robert, he's so gorgeous! Studies show that married women agree with me.
