Nietzsche is the champion of skepticism and intellectual honesty.
His conclusions are not always pleasant, but always honest. He does not bend reason to reach cute conclusions, he does not mince words, he observed, thought carefully over many years and questioned. He questioned absurdities very few notice, like why do we even care about truth. He saw everything metaphysical and morality as inventions.
At a first glance he seems mad and out to provoke, but that impression is erroneous. If you afford him the benefit of doubt, test out his ideas and you yourself are able to be intellectually honest, then I sincerely believe your worldview only can become what Nietzschean, not in detail but in general. N had his tastes, and you do not have to share them - you can to desire equality or whatever you feel like, Nietzsche does not forbid you from having moral feelings, what he does is demolish the idea that morality has a metaphysical existence.
Sometimes N gets speculative, in a few sentences he might present a convincing account of how Christian morality formed - but he does this so briefly, with so little evidence, that it is shocking. He must have thought about these things for years and discussed them so much, that he could pick a few sentences that would convince an erudite.
He has earned my confidence.
