Oat milk is my favorite. I enjoy Oatly Full Fat the most.

I grew up drinking rice milk, which was good in cereal, but on it’s own tasted a bit watered down. Texture wise, it’s a lot thinner than oat milk. Rice milk was still good, but just drinking it plain was only alright, oat milk is so much better all around. I haven’t had coconut milk, but I’m not a huge coconut fan so I have no intentions of trying it. I can’t drink almond milks, or other tree nut milks., heard they were good though. I have had soy milk, and it is alright, but I still find oat milk the best.

Also this may be better suited on /c/vegan, Edit: Oh, I just realized you cross-posted.
