Not sure what you mean, but here are some considerations. See which is important to you and then others can opine?

Taste (subjective. E.g. I find anything that is tetrapak vs refrigerated to have a ubiquitous off taste)

Versatility
(some hold up better in hot liquids than others; or have a necessary thickness for cooking or baking)

Nutritional Profile
(soy is usually naturally higher in protein; oat and rice milk are high carb / glucose load)

Cost

Quality of ingredients, including how processed they are

Inclusion of undesirable ingredients
(e.g. oils, thickeners)

Ecological impact
(Amount of water to produce e.g. almonds vs oats; over harvesting e.g. coconut)
