I voted for Tiefling, but it could have just as easily been Dragonborn, I guess. Not really relevant to me and my players.
My players and I typically don't consider any race core except human. Maybe EVERY once in a while someone plays a non-human. We dislike high-fantasy campaigns where where every single town, no matter how big or small, is a virtual Mos Eisley Cantina of half-this, half-that dragon, dark elf, demon weirdos walking around like regular joes - this one runs a weapons shop, that one's the local wizard, etc. Humans are the dominant race, but even their settlements are few and far between. A dragonborn settlement? Just a legend, hidden up in the mountains somewhere. Finding it might take ten levels and result in campaign-world changing events, after which someone plays a dragonborn. Even then, he'd be one of a kind, a bizarre phenomenon attracting attention everywhere he went. Anyway, as a result, we haven't really generated too much ill-will against the other races. Simply put, they're just not that relevant. When we do run across one, everyone's excited and curious - not irritated.
