Is this even up for debate? There is no sugarcoating it: the UFC, the pioneer of mixed martial arts, is still the sport's foremost promotion.
Who has most of the top fighters in the world? Who has traveled to the most cities and countries in the world? Who attracts the most media coverage of any MMA promotion? Where do most MMA prospects strive to fight in when they grow up? There is only one answer to that - those three letters above.
Beyond the fights, look at the video packages. Embedded, Countdown, even all the other small stuff - only the UFC, with its abundance of resources, can produce such compelling content, no matter the scale of the fight - whether it be a championship main event or a clash of newcomers just starting their journey.
Say what you will about Dana White as a person, but as a promoter, he has a top-notch game.
