How do you feel about cheap bottles of pop?

We tend to go for mid range brands like Lowes and Barr rather than the pricer ones like Schweppes or coca-cola. We're happy to drink supermarket own brands too. Given it's just water with pretty much the same chemicals added I'm not sure what I'm gaining with the premium brands at twice the price.

Thoughts?
