I've already got a cheapy TPU case to get me through the first few days of owning the phone, but I'm pretty sure I'm going to want something that will provide better protection. I can't decide between the Otterbox Commuter or the Case-mate Tough cases. I used to have an old Otterbox case for a different phone and found that the silicone started to degrade pretty fast. Does anyone know if they have improved this? And which one do you think is best and why?
