I can't stand canned US coke. I have to drink mexican coke, which is sold at Homedepot near me. They seem to be selling those at $1 per bottle pretty well.
I believe, but could be wrong, that the differentiating factor is that coke from Mexico is made with sugar.
J. Kenji Lopez-Alt did a study where he concluded that people who think they like Mexican Coke more than Regular Coke simply enjoy tasting Coke out of a glass, and the perceived cane-sugar vs HFCS may just be a placebo:

But YMMV. Even having read that study, I still prefer Mexican Coke.
