All sodas, and especially Coke, are pretty transparent that they adapt their formulations by region, plus the water chemistry is different everywhere, so they have to adjust for that too. Labeling laws are also different. I therefore cannot put much stock in anecdotal reports of people finding that one continent's version of a product tastes different than another continent's. In my experience, that is true of every food product there is. My observations come from the US market where brands have often been producing cane sugar "throwback" versions of their sodas in the same bottling plants and for those the sodium content is listed as being a bit higher. Probably that is not the only changed ingredient though.
