Coke Zero vs. Diet Coke

What is the difference between Coke Zero and Diet Coke? Naturally, for a serious question like this, I went to the Wiki:

Coke Zero is "a low-calorie variation of Coca-Cola Classic sweetened with aspartame and acesulfame potassium (also known as Ace-K)."

"Diet Coke does not utilize a modified form of the Coca-Cola recipe but is instead an entirely different formula. The controversial New Coke, introduced in 1985, used a version of the Diet Coke recipe that contained sugar and had a slightly different balance of ingredients."

So the difference is rather simple; Diet Coke is New Coke with nutrasweet and Coke Zero is Coke Classic with nutrasweet.

Note, neither match up to the real thing, which in the Styx's opinion, is the greatest soft drink in the universe. But, that just may be my logo talking.
