I can’t remember the last time I had an actual glass of plain water however these are both quite enjoyable. Since they both arrive carbonated I can comfortably assume that the pH is low enough to ensure that there is nothing living in it before I drink it. I do not feel the same about even our zero filter water dispenser unless used for cooking. The soda stream or even some of the new reverse osmosis carbonators are also a good alternative. If you don’t like it plain I would stay away from their flavors and stick with a little bit of apple juice or similar as someone suggested. And also as someone suggested you should probably try to limit the diet stuff. I agree with the caller it is addictively unsatisfying. I know I live with a diet Coke junkie, but she is now shifting more to carbonated flavored waters.
