Is Otterbox or Lifeproof better?
Both Otterbox and Lifeproof are better cases because they cover the devices in way that protects them from, direct sunlight, hazardous materials and moisture amongst other things.

I prefer Otterbox, but Lifefroof works just fine, as well. You cannot go wrong with either.
I've have an Otterbox, works pretty well, I've tested it many times
Lifeproof for sure. Dropping your phone on concrete or in water won't hurt it, which is better because Otterboxes won't protect your phone from water.
