That's a tough question, do you want thin, heavy duty, water proof? There are so many out there to choose from, really goes on your taste. For me I just got a cheap one until Otterbox comes out with theirs. I work outside and need a tough case.
I usually get an Otterbox. However I just ordered a Spigen case and I'm waiting for it. Also want to try out Lifeproof.
For now, I've got a clear Insignia case on until the others arrive.
