I ordered a set from eBay with the colors like Joe's (2nd post) and I returned them as soon as i saw that there was another seller selling them with a "Metallic" color look.
I just installed them today and i love them.
I'd say that the metallic ones have a more "Premium" look.
Heres a comparison, as I said... I went with the metallic look and Dual fins (f80) grill
