Cases that are simlar to the Speck Pixelskin HD (iPhone 4/4S)?

Hey,

I really like the look of the Pixelskin HD for the iPhone 4/4S.
Are there similar cases that are better or is this the best option?

EDIT: Maybe the Spigen Modello?

Is also saw the GeoSkin on the website of Speck.
Is it thicker than the Pixelskin HD?
