That's a poor comparison - just because the universe is amoral, doesn't mean we have to be. There's two parallel paths that I see people confuse all the time, that of how the world is (truth) and how we should be (good). Nietzsche is interesting for talking about truth, not necessarily good. Practical philosophy is just telling you what is good, and so far I haven't seen a moral framework that is competent at that. Especially utilitarianism. Partly because I think the idea of a moral framework is reductionist, but this isn't the right place, nor perhaps you the right counterparty, for me to lay out my issues with reductionism.

Tldr: yes I think Rand is a poor moral philosopher too.
