I prefer any plant based option - oat, rice, almond, hazelnut, cashew, quinoa, hemp, coconut, flaxseed, etc. The waste from a ram of 2,500 dairy cows is equal to that of a city of 411,000 people (Miami, Oakland, Minneapolis, Raleigh) (x), and livestock produce 7 million pounds of excrement every minute (x). Additionally, animal agriculture is responsible for 91% of amazon deforestation (x) - and uses 1/3 of the earth's entire fresh water source (x). I used to absolutely looooove my milk but it makes me sad to think that I'd drink litres at a time without realising what I was supporting.
your c*m is probably more healthy and tastier then the milk people drink at their local grocery store.
