UAG looks interesting, i'll probably check it out. The reasons i choose these 3 are:
1. Rhinoshield offers a best-in-class drop protection of 11ft and was tested up to 25ft. It also offers great customisations.
2. Otterbox is a brand that everyone knows and trusts. The con is that it is the most expensive and there are some reviews in Amazon about it not having enough drop protection?
3. Caudabe is a relatively new brand but there are many positive reviews about it.
Any particular reasons you would recommend the Otterbox over the other 2?
