Otterbox used to be my favorite case (from the 3GS) and for the Galaxy S3 but lately their products for the more squarish iPhone 4/5 have been less than stellar.
I started to like Otterbox again. At first their cases were a little bulky for every day use but the new case for my Galaxy Note 3 is slimmer and feels fantastic. I'm waiting on a review to see if Otterbox has been keeping up with that with their new iPad Air case.
