Whole definitely.
2% and 1% fail completely. Skim is OK because it is like water with white coloring. I don't like 2% or 1% at all because you get the expectation that it is going to taste good, and it fails miserably. At least with Skim, just by the looks of it you can tell its gonna taste like water, and for the most part it succeeds in doing that.
I don't care about price, but certainly, i grew up drinking whole milk. It tastes good, and there are worse things for me (soda) that I drink for whole milk to ever enter the picture as someting that might be unhealthy.
