Jones Cola is decent. But its overly expensive. Most Off brand colas are pretty bleh. but I drink them anyway because that is usually what stocked at my house hold and I like cola too much to just give it up.
As for Pepsi and Coke, I like both more than off- and store-brands 99% of the time. I like Pepsi a little more than Coke but Mexican Coke (comes in a glass bottle, real sugar) is slightly better than Mexican Pepsi (also comes in a glass bottle, real sugar).
Really I'm a cola person. But outside of that not really a soda person. Root Beer is ok but it feels incomplete to me in most cases with out some vanilla ice cream mixed in.
Dr. Pepper can be ok as an occasional break from the normal cola, and it used to be my favorite drink. but its rare that I'll pick Dr. Pepper.
Sprite/7up/Sierra Mist was the first Sodas I started to really like. Oddly enough though I stopped liking them too much and now very rarely drink any at all. (plus its supposedly 7 times worse for my teeth than non-citrus soda)
I know exactly what you mean, the only fizzy stuff I drink any more is coke/pepsi (and dervatives like max, vanilla, orange, cherry) otherwise I prefer stuff like apple juice or orange oasis (doesn't leave that dry feeling in your mouth like most drinks) I do occasinaly drink fizzy orange (mirrinda) and fizzy strawberry (mirrinda) but there only every now and then.
Untill it was mentioned, I had no IDEA that there was a drink called pepsi RAW.
I wish I knew where to get strong tasting root bear where I live.
