Benefits of drinking soy milk instead of regular whole milk?

For some reason I just can't tolerate drinking regular milk. To me it's not tasty at all. The only kind of milk I can tolerate is soy milk. What are the advantages and disadvantages of replacing cows milk with soy milk? Will I still be getting the same vitamins? The brand of soy milk i usually drink is Silk all natural soy milk with DHA omega-3.
