Nobody does sibling rivalry like The CW. So who's hotter: the Salvatores from "The Vampire Diaries" (Paul Wesley and Ian Somerhalder) or the Winchesters from "Supernatural" (Jared Padalecki and Jensen Ackles)? We're going to have to do some intensive research. It's a difficult task, but someone's got to do it.
