I've used the OtterBox defender. It's a very durable case, but the rubber price got loose pretty quick. I switched to a couple different cases without the built in screen protector including the OtterBox commuter which in my opinion the lack of a built in screen protector was its only downside. Right now I'm using the Trident Krackon Series (probably spelled that wrong) it has the built in screen protector as well as a metal kickstand. I've only had it a few weeks but so far its turning out great. Word to the wise though if you get a case with a built in screen protector you should also put a
regular screen protector on as well, because dirt and stuff can get underneath your built in one and really screw up your screen. I hope this helps.
