I personally like my iPhone naked but I never really liked babying my phone and wanted to keep it in like-new condition (for resale) so I'm forced to use a case. I've tried so many cases for my 4, the only one that I felt confident in for protection was the Defender case by Otterbox. I never tried LifeProof but a couple of friends got them and had nothing but problems with them. But lets face it, the Defender case Otterbox made for the iPhone 4/4S sucked big time. It was so thick and bulky but that wasn't even one of its main drawbacks. The rubber was loose and loosened even more over time which made the case feel horrible and cheap, and the type of rubber they used was a lint magnet. Every time I took it out of a jacket pocket it was just drenched with fibers and lint. Also, the port covers were really pathetic, flipping open on their own, almost impossible to secure in place. And the screen protector just gave the retina display a muddy look. I was very hesitant to try out the new Defender but I needed something interim while I researched a good case, and I thought I'd try it for a few days and if I didn't like it I'd then return it. Well, I'm in love with this case. Otterbox seems to have actually listened to their customer complaints about the old one because they've literally addressed every issue I had with it. Even though the new one is of course taller, overall the case feels quite a bit thinner and pocketable. The rubber is much firmer now and fits perfectly, I can't imagine it ever loosening. Also the rubber now has a slick matte finish to it, so it doesn't attract lint at all. Best of all, the ports are very secure, almost hard to open now which I much prefer to the way it was before. And the screen protector, while not quite as clear as say an SGP Ultra Crystal, it's very good and definitely usable. The only negatives I found, and I'm reaching here, is that the opening for the rear camera/flash and front opening for the earpiece and camera are really big so if the case does end up placed with keys or other sharp objects, there is a chance they will come into contact with the camera lenses which may scratch them. But all in all, it's a great case. I highly recommend it.
