1. Original---Best when it's ice cold, even with a bit of ice forming inside the bottle. I typically put it in the freezer until it's at that almost-frozen state.
2. White Out---If I could find this on a consistent basis, it might challenge original for the top spot on my list. But I haven't been able to find it anywhere in a long time.
3. Live Wire---Nice change of pace to original.
4. Voltage---I don't drink it often, but when I do, I usually find myself thinking I should get it more often.
I don't mind Baja Blast. In fact, when I infrequently go to Taco Bell I usually mix 40% original, 40% Baja Blast, 20% pink lemonade. I like that mixture a lot. I have tried some of the newer flavors, but haven't really liked any of them very much (Spark, Thrashed Apple, Major Melon, etc.). And, although I know it's very popular, I have never liked Code Red.
That is all.
