I have always preferred the consensus protocol of Proof-of-Stake compared to Proof-of-Work because i believe that true decentralization is achieved on PoS. Just recently the Ethereum Network upgraded to PoS consensus mechanism yet i have not heard about the specific collateral coins that would be required by the network to host a node. I would like to know how they intend to use the PoS as its consensus protocol knowing that currently its supply is not capped yet.
True decentralization is not achieved anywhere. At POS, most coins are concentrated at a small part of addresses.
Therefore, the best option is a combination of POW and POS.
