Really??? King of Smokers, Sam's, World Food Championships??
Not to disrespect people's opinions but, they've only been around a couple years. You'll find just as many (if not more) teams with amazing track records at the Jack, MIM, and the Royal.
Not to discount those contests, but the prestige of contests is built by the skill of the teams competing AND age. In order of oldest to youngest: The Houston Rodeo, Memphis in May, the Royal, and the Jack are BBQ institutions...that creates prestige.
Wait ten years and ask this question again...I bet you ten bucks the four listed above will still be around, and still be considered the most prestigious in BBQ, where as many of the others; Sam's, World Food, King of Smokers...will be in the ash pan. I hope I'm wrong, but I don't see them lasting the decades the Legendary 4 have.
