Parralels between Nietzschean morallity and Buddhism and their paths towards enlightenment

At first glance both of them might seem like 2 fundamentally diametrical opposites. Nietzsche believed that a fundamental truth of life was that "the strong always oppress the weak", and that morality is simply another means through which this is achieved (Christian morality vs the nobility). Throughout his books, he heavily critizes the idea, that an objective truth and morality exists. He therefore rejects the absolute value of morality and comes up with the will of power, which ultimately guides all behaviour. The Ubermensch is the person who lets his behaviour be guided by the will of power and is not contstrained by morality, the idea of The Overman being the Nietzschean interpretation of Enlightenment, you could say. Ultimately, a striking similarity between them is the lack of objective morals - according to buddhism, what is deemed good or not is relative to whether it brings an individual towards enlightenment or not, meaning that it rejects the idea of objective morality (corect me if im wrong). I think that both philosophies perceive morality in an utilitarian perspective, not an objective one. They both make the individual want to strive towards enlightenment, the means through which it's achieved being subjective and relative to each individual.
