I have no preference on race, as each one of them has their uses. Humans makes good soldiers. While they have weak Psi Atk, I hardly use that feature anyway. The good stats are even enhanced by the fact that it could be constantly improved, hence, making them the best overall troops. However, late game, enemy Psi attacks are frequent, and no one likes that. Especially Humans. Hybrids, well, since I don't use Psi, I often times leave them training in bases(Physical Training), and use them mostly as some sort of base defence(along with a few androids). Androids are great early in the game, but despite the static stats, they are still important enough to have latter in the game. Since they have no organic brains, they cannot be Psi controlled, so they are immune to one of the more hated enemies, the PsiMorphs and their ilk. Also, Androids are good in the early games in missions where the enemies are Brainsuckers and Anthropods. Since Brainsuckers can't do shuckeroonies to Androids, and even better, the Anthropods are all armed with Brainsucker Launchers, they can breeze through the mission. Just be careful of other threats as well, like those Hyperworms.
