Coke Zero does not taste like Diet Coke.

Diet Coke is sweetened with aspartame; Coke Zero is sweetened with aspartame and acesulfame potassium. Using two sweeteners keeps the concentration of each below the threshold, where you notice any "chemical taste", or aftertaste. Apparently, I'm not the only one who notices the improvement.

I agree. Coke Zero always leaves an ugly aftertaste that I don’t get with Diet Coke. It also seems less fizzy, but that might just be my own taste buds.

Same here. I can't stand the taste of diet Coke, but I could drink Coke Zero all day long

Major taste improvement.

Yes, I have always hated Diet Coke, but I adore Coke Zero. I especially like it with bourbon. :D
