I'm using the Otterbox Defender as It's pretty rugged and has a holster clip. So far no problems. I just don't like carrying a phone in my pocket, just my preference. I used a Otterbox Commuter on one of my old phones and really liked it better, but has no holster. The one thing that I really liked about the Commuter was the phone slid into a rubberized case with a hard plastic shell that went over it. With the Defender, the phone goes into a 2 piece hard shell and then a rubberized outer shell goes over it. I've had good luck with both.
