Sure thing, let me try to explain:
The Tones is a very good case. It doesn't add much bulk and it's consistent and makes you feel your iPhone is protected. I like the design and feel of this case but it only has one downside for me: the material the case is made of is soft and if you're not careful, it might slip from your hands. Apart from that, love this case.
The Belkin I have is the one from the picture but I have a white iPhone 5, and you see a little bit of the back, but not too much. Its made of a adherent material, so its grip is good and it won't slip from your hands as easy as the Tones.
All in all, I love both but since I've been using the Tones since day 1, I switched so I have the thin Belkin case so I can "feel" more of the iPhone.
Hope this helped
