As I’m drinking Coke Zero, I thought I’d throw my two cents in. First, I only drink Coke Zero when Diet Coke is not an option. That should give you an indication of how much better Diet Coke is: it’s the one that runs out.
Yes, I can taste the difference.
I would put Coke Zero as closer to Diet Pepsi, although it’s better than Pepsi. (Yes, I can taste the difference. So much so that I won’t order Diet Pepsi anymore. I’d rather drink water for free. Sorry Pepsi fans.)
I will drink Coke Zero if it’s my only soda option, especially today when I have to go for bloodwork and can’t get a McD sweet tea (which I drink about once a year).
So, there you have my unscientific analysis.
