Wouldn't if be more fair if we'd compare to each character's equal?
I love both body's a whole lot. It's just the thing that - for me - Jacob wins because his body looks amazing and it fits perfectly for his character ( So he's waay too young, can't deny the boy has a cute face and a delicious body )
Edward's face is manly and sexy but his body in Italy... pale white as he is with the black hair... ain't THAT appealing. But fits perfect as a vampire body. As Rob... he is scrumptious yet a tad too skinny at times..
