My parents got me an iPhone 4 last September, and I was adamant that I needed an Otterbox case. I got the Defender case, and my dad got the Commuter. I've had my Defender case on my phone since I got it, and the case is just now starting to show wear. The rubber is tearing on a few of the flaps, and there's one chip on the base. I was not as impressed with the Commuter case. One side of the rubber never seems to sit properly, but it's been fine for my dad and my mom, who now has the case. I have dropped my phone once or twice, but it has absolutely no damage.
