Debate on Which Case?

[Demarrer]

With my G2 Iphone, the case i bought scratched the silver around the screen of the phone, and i have decided on one of two cases for the Iphone 3G S.
I was wondering if anyone knew if either of these cases would scratch up any part of the phone after time... Thanks.

I've heard great things on the SwitchEasy cases.

Quick question, I have a black 8gb 3g, I was wondering what this would look like with the SwitchEasy Colors in Milk colour? Any pics would be much appreciated.
