I am not "the best" at anything. I can do a few things adequately. I can drive a 5-speed on the steepest hills in San Francisco. I can captain a sailboat. I can do a back handspring (at least, I used to be able to do this). But that's hardly "the best."
When most purists talk about "real" cooking competitions, they mean the Culinary Olympics, the Bocuse d'Or, or lesser known contests organized by national foundations such as the American Culinary Federation.
