I did read about soy possibly being "not so great" but same as you, I find nut milks very expensive, and not available around here unless i make my own, which probably will not happen. To buy enough almonds to make it myself would break the bank.
I drink "milk" very very seldom, but will use soy occasionally for cooking, and for my sons cereal he enjoys.
It may not be great but it's the lesser of two evils in my opinion.
