I own the Incipio NGP and it's wonderful! Most of the complaints on Amazon seem to be from when it was first released because I have had zero of the issues the reviews mention. For example, the power button is extremely easy to push. I'm pretty sure incipio revised the case.
if you're looking for a rubber case that isn't basic, then I would check out KaliCases, I got one for iPhone 6s Plus and I love it! I've dropped my phone a few times sadly too and still going strong haha.
