Different strokes for different folks. I personally never liked otterbox due to it's bulkiness and never used one. My wife had one for the iPhone 4S and it made it fat (no offense but not my taste). I prefer the Spigen Neo Hybrid cases.
To continue, I wanted a clear case so I could see the pattern on the back of the phone, and it's a slim but rigid case, giving some protection but also looking good.
Thumbs up for the UAG case. Had one for my s3 and now on my s4. Buttons work perfect, protection is great, dropped it several times on my driveway, no problems! My husband got one also for his note 2
