As you’ve presented it, the vegan has poorer nutrition than the other person. We also need to consider the vitamin supplements to get amino acids we only get otherwise from meat.
Soy is a complete protein, meaning it has all essential amino acids.
Seitan has 8 out of 9 essential amino acids, is made from wheat and has about the protein density of beef or chicken (~25% according to a quick search).
You get a ton of soy and wheat which would otherwise be feed to animals. Just make tofu and seitan.
However, you’re right, you need to supplement some things - at the very least B12. Which a non vegan diet mostly gets from fortified products, meaning its supplemented anyways.
