Has anyone tried the new Diet Cokes with Splenda/Sucralose and/or the new Coke Zero (Diet Coke with more aspartame/Nutrasweet)?

Diet Coke Splenda is way sweet and Coke Zero falls in between Diet Coke w/Nutrasweet and Diet Coke w/Splenda.

To add my two cents: I try to minimize HFCS whenever possible. Not that I think overloading on regular sugar is healthy either.
