I drink Diet Coke and recently tried Diet Coke with Splenda. Thought it would be better, but it was vile. To some people, it probably tastes more like regular Coke, but to me, it tasted way too sweet, like chugging Coke syrup. It might be pretty good with half the sweetener, but people are so used to getting too much sugar and too much salt, if you dial down either one, they complain there's no flavor.
