Poll: Whats your favorite diet soda?

I'm going on a all liquid diet for 2 weeks.. and although I have to drink mostly protein shakes and water I can also have SOME diet sodas. I have tried Coke Zero.. it's okay. I've also tried Diet Dr Pepper.. it to is okay but I don't think I could bring myself to reach for either one.. tonight I tried Sprite zero for the first time and it was amazingly good! Tastes IDENTICAL to sprite! It's the best diet drink I have found so far! Has anyone found any other good diet drinks? How is Diet Mt dew? Thanks for any input
