I prefer satin personally, but don't mind any of the others (that I've seen thus far) except the black finishes. I think they look cheesey and invite trouble from LEO.
I understand that a lot of people buy them because they think it makes them look cool because the black coatings are associated with all the "covert", "spec ops" stuff, but it's this same association that's gonna make it tough for a LEO to believe that you're not carrying it for some illicit purpose.
