Glass Bottle FTW. You can find Glass Bottles of ANYTHING you want here. Maybe because we have a Coca-Cola and Pepsi plant in town though.
Plastic Bottle < Can < Fountain < Glass
Fountain and Glass are much more refreshing, while I find that can and plastic isn't. I really don't like plastic at all because it doesn't hold onto its coolness. Once it comes out of the fridge or soda machine, it gets warm ASAP. Glass takes a bit longer to get warm and a can isn't as good as glass in these terms, but it holds onto it longer then plastic does.
Though I do try to stay away from Soda as much as possible! Very bad drink for your health.
