I'm completely honest here, I never ever wanted to look like someone else.
I always wanted to improve aspects of me, but downright body-snatch someone? Even a person who "objectively" looks better than me in every aspect? Nope.
However, if I would be forced to bodyswitch, like, we are in the future and I'm terminally ill, with the only option being my mind transferred into another already existing body...
then it would be the guy from White Collar.
I don't think it's possible to look objectively better than this man. He has no cool features, that make him unique or anything, but he is a safe bet.
