They taste like they are watered down to near no flavor compared to the fountain diet cokes.

Fountains can adjust the strength of the formulation (syrup to water ratio). I do not know if this is still the case, but to save money, fountain Diet Coke and Diet Pepsi had continued to mix saccharin with the aspartame long after they went all aspartame on the cans and bottle. No labels on the fountain drinks.

Fountain drink quality varies. Those 100 in 1 machines at Wendy's and other outlets use powder instead of syrup. It makes a difference,
