The most popular soda is Coke, which comes in two no-calorie flavors: Diet Coke, and Coke Zero. Diet Coke uses asparatame exclusively. Coke Zero uses asparatame plus a newer invention called Ace-K. Most people prefer the taste of Coke Zero, because it's more like normal Coke. Other sodas' "diet" varieties typically follow Coke's naming and use just asparatame. I wonder if soda companies are not just rebranding, but also looking into reducing the asparatame taste...
