The bitcoin white paper explaining POW is relatively easy to read and reason about, even if working out how things will actually play out in reality might not be. I've yet to see anything similar for a POS consensus mechanism. It just inherently seems more complex and for that reason I'm out. 

 That’s bc PoW is for autonomous consensus, while PoS is for leadership and direction.

Conflating the two is where the mistake is,  it that one is better than the other.
