Coke wins, its just got superior taste, and is a classier brand
Dasani lol, I remember when that stuff came out in England, they banned it from sale after about a month when someone pointed out that its just jumped up tap water. I wouldnt imagine they are using anything of a higher quality in the US and Canada.
Read this!Dasani Wikipedia
Read the bit on Dasani in the UK. Shows how Coke's cackhanded purification technique somehow made safe tap water into possibly carcinogenic bottled water. Absolutely shocking!
Coca Cola still owns though!
