Bough the Defender for the face-in clip holster, forgot how much I hate clip holsters because of the added bulk and it digs into my ribs when driving. The case is absolutely a tank. It has saved the phone various times from disaster and has the character marks to prove it, but I went back to the Commuter for various reasons:
1. The clip holster reason given above. I bought a cheap leather holster that fits the whole phone with Commuter case installed. perfect..
2. When using the phone in low light conditions I have to remember where the home-back-menu-search buttons are because they are no lighted anymore.
3. The headphone jack and charge jack covers are a pain to reposition. I find myself fixing the fit all the time.
4. It adds a lot of bulk, a lot.I don't mind the bulk has much because it's added protection.
Overall those are easily overlooked peeves if you want the absolute best in protection, but I found the Commuter/Leather holster combo a better suit for me.
