I went with the non-skid, and the extra grab handle on the rear (it comes with side grab handles), and they are using shelf brackets in the center for support.
When we called B-Bracket they said they would paint it from the paint codes used by cigarette so it would match. They did not mention powdercoat. Extreme told me they powdercoat all there platforms. Both make a nice platform, and if B-Bracket is willing to powdercoat I think either one would be a good choice.
