Whether Miller Lite is better than Bud Light, now that is a loaded question that is certain to lead to arguing. Though one fact that cannot be disputed is that the ORAC (or antioxidant content) of Miller Lite is 12.5% higher. But that isn't saying much, because even a Domino's cheese pizza has over 2x the amount as both, when based on an equal weight to weight comparison.
