Zero or Max?

I passed by two large posters within steps of each other on my way home. The first one was that of Coke Zero, the second, Pepsi Max. I find it interesting how each company decides to market these similar products using different angles. One emphasises on the drink’s maximum taste (sans sugar), the other on the lack of calories (while retaining its original flavour):

Pepsi Max — Maximum Taste, No Sugar vs Coca-Calo Zero — Real Coke Taste, Zero Calories 

It could well be Pepsi None or Coke Full. Maybe even “Pepsi No!!!” or “Coke Real?”. I amuse myself with silly little thoughts sometimes.

Which do you prefer?
