I would say it's more congruent with evolution, which is to say it aligns with the idea that mutations or other advantages can put an organism far ahead of its competitors and improves the species through genetic preservation (or historical preservation, in the case of societies).
I don't buy that it's out-and-out better than a collectivist system at a society level (even though I consider myself very much an individualist). As usual with these sorts of polarising perspectives, the ideal is probably somewhere in the middle and a purely individualist society will never be able to persist long term.
