I've actually used my black iPhone 5 for weeks now. And I'm actually a very rough user, tend to leave it on tables, pockets with keys and I even dropped it on solid ground (from table height) a few times before but there aren't any scratches or scuffs at all so far.

I'm using my phone totally nude btw no protector casing bumper. It's a Singapore set.

So I guess sometimes its all depend on luck I guess regarding the scuffgate issue.
