I hate to throw a monkey wrench in this lively debate, but for a point of clarification not all 4WD Wranglers come with the badge. Some special editions don't ... at least one that I know of. The 2011 JK COD Edition is a blacked out Rubicon. It didn't have any of the standard badging (e.g. Wrangler decal, Rubicon decal or trail rated badge).
Hmmm debadged and blacked out is a good way to market to virgins, good to know.
