Like has been said it's a mute point since obviously no one can say that whey is better or casein is better, it comes down to choice.
Thanks for the replies Guys
I know you are trying to just let this thread die, but I thought it worth mentioning that "protein" is not just "protein" any more than carbs are just carbs. I think that is the point Aaron was trying to make.
In your defense, when comparing the cost of powdered milk to "milk protein isolate", powdered milk is clearly cheaper. This is because it requires very little processing to produce powdered milk compared to "milk protein isolate".
Here are some references dealing with the point Aaron was making. Not that you aren't already aware of them, I am just adding them here for others who might not be.
