iPhone 5 backside design - White (ceramic glass) vs. Black (pigmented glass)

[saintforlife]

From the Apple site:

The back of iPhone 5 is made of anodized 6000 series aluminum — the same material used in Apple notebooks — with inlays along the top and bottom made of ceramic glass (on the white and silver model) or pigmented glass (on the black and slate model).

Any thoughts on whether the ceramic glass (scratch proof?) on the White model is better than the pigmented glass on the Black model?

Well, I currently have the black 4S and it is pristine.
