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.

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

Major taste improvement.

I drink iced tap water all day long.

Cheap and healthy(at least in my area).
