Oat milk is really good too and is usually cheaper than almond milk, at least where I live.
I normally prefer soy for flavor, with oat as a close second.
For nutritional value, I think soy is the top, followed by pea, and oat way behind.
For environmental impact/needs, I think soy and oat are also among the best.
Soy milk is a miracle food and we should embrace it.
