I was very lactose intolerant and tried everything to various degrees of success.
1. Almond milk: tasty and not too sweet.
2. Rice milk: very tasty. Too many carbs.
3. Coconut milk: weird taste. I did not like this.
4. Soy milk: disliked originally but eventually found a vanilla soy milk that was decent.
5. Goats milk: disgusting taste.
I think there was a couple others but nothing stood out.
I adjusted my protein intake and reduced my carb consumption a bit. The lactose intolerance has virtually disappeared and as such I drink organic cows milk. Yum yum
