I made no assertion about the taste of sugar vs. corn syrup. There are a number of products marketed as "Coke", and those products have different flavor profiles. Some use sucrose, some HFCS. It might be formulation, it might be packaging, freshness or bottling methodology. Maybe they don't tweak formulas for limited run products or in local markets like Mexico. I have no idea.

Even with the standard fountain formulation, there is a different/better flavor at McDonald's because of the standards they apply to each part of the supply chain. In a few weeks, depending on where you live, there will be two liter bottles of coke with a yellow cap. That's kosher for passover -- try it.
