I personally like the flat black look - gives it much more of an "industrial / off-road" vehicle look than the glossy Ebony. When the Ebony is all detailed it looks like a mean "street machine" to me, even with the lift, 33's, and the rack.

The Herculiner on the other hand is a bit too shiny for my taste. I'll probably spring for some Line-X if I ever get mine done.
