Soy has always been my favorite. I mostly drink plant milks on cereal, and I feel like it works better flavor-wise and has the creamiest texture, but ultimately different people have different tastes.

I've never tried a variety that tasted bad at all -- oat, flax, cashew, rice, hemp, whatever -- they all taste good to me.

Oh yeah. I didn't think there'd be many of them here though, but I never really understood that in the first place!
