At school I find that rice milk tastes better. It's more thin and more sweet. Then again, I forget whether we have silk soy milk at school or another brand. We have Rice Dream for rice milk.
Rice milk naturally lacks the protein and calcium that soy milk inherently has, so it's good to get fortified rice milk. Rice Dream is fortified with calcium, B12, and other vitamins, but it has no significant protein. And in considering the drinks I have in addition to soy milk, it's nice that rice milk doesn't give you canker sores, unlike orange juice!
Hm, almond milk sounds interesting.
