Well, whey is primarily derived from animal milks.

Soy is from plants.

Since we evolved as meat eaters I don't think it would be a stretch to say that we absorb and translate energy and other signalling more from animal type proteins better than plant protein.

I don't know the particular amino acid compositions of whey and soy respectively, but I do know that whey contains at least a significant percentage of BCAAs which has been shown to have favorable effects during exercise and metabolism in general
