Is there any technical literature on why PoW is better/more decentralized than PoS? Or, vice-versa? Or, which is better under which circumstances? Or is it all just maxis yelling about it on the internet?

Reasonable people can disagree. The difference between PoW and PoS is more about the security budget than decentralization, though. PoW has to market-sell their security budget at all times, PoS can have much higher security budget as they at most sell the yield.

Ethereum

Some say Proof of Stake is more centralizing than Proof of Work. You and I know this isn't true.

But did you know that PoW is theoretically (and possibly in practice too) more centralizing that PoS?
