My source tells me both have both aspartame and ace k (Acesulfame potassium), but their flavour formulation is different. Diet Coke is meant to be a little different from Classic Coke, while Coke Zero is meant to mimic Classic Coke. So we were all a little right and a little wrong.
I think they only put aspartame in Diet Coke but I could be wrong
