I saw the matte black at Target and loved the look and feel, but have been leaning more towards the Griffin Clarifi lately. I don't care for the partially glossy middle, but do take quite a number of photos of product tags and the macro would come in handy.
I returned two matte black ones due to the matte finish peeling. The second time I replaced it with a gunmetal one, and haven't had a problem at all! Go with the gunmetal.
