I researched these cases inside and out when considering one for my iPhone 5s. Ultimately, I was disappointed with all of the cases' shortcomings, and didn't end up getting a waterproof case. Among the options, I prefer Lifeproof. They tested better, and seemed to have the one best feature - your phone is still functional whilst in the case. Not to say the Otterbox is not, but it is significantly more bulky to carry and use. For aesthetics and protection, as I couldn't stand the idea of having no screen protector like the Nuud, I came to liking the Lifeproof Fre the best of all of them. I've still considered picking one up on occasion, but fortunately haven't needed it yet. I'm sure someone who's used these cases will happily contribute, but these are the conclusions to which I came from my extensive research. Best of luck in your shopping!
