Soy vs Whey Protein

Options
I've notice a lot a people use whey protein rather than soy, is there a major difference or is it based on personal preference?

    Some people do not like soy because GMO'd. Some don't like soy because it can interfere with hormones. I choose whey because it's cheaper !
