The Otterbox Defender is possibly the best for drop protection....but it lets grit into the case and scratches the phone. Do not buy it, unless you’re going to take it off every couple days to clean it out.
The Lifeproof Next and Fre are excellent cases, and extremely tough. Also, customer service is excellent. If you have a problem with your case, they’ll send you a new one every time. That offsets the higher price. I’d get one of those, and a glass screen protector.
