A friend's choosing which 5S to get. I couldn't recommend getting a 5 in black to anyone who doesn't plan on keeping it in a case due to how scuffs show up on it. Since the 5S has been out a while can people tell me how well it's stood up to wear compared with a black 5? Specifically people who had issues with their black 5 scuffing up - if you managed to keep your black 5 pristine without a case then... wow. It doesn't matter much since my friend intends on putting it in a nasty ugly case, but I'm still curious.
