In your opinion, what is the best?
Most of these consensus mechanisms in your OP has at least one or all of these, which is it is centralized, permissioned, prone to censorhip, supports identity exposure and has weak security for its blockchain, and the cryptocurrencies that use some of them are small and unsafe. But the BTC proof of work consensus mechanism is decentralized, permissionless, very secure and censorship resistant, because anybody can become a node or a miner without any verification, so which is the best?I totally agree with you. And what if we bring it to the TradFi world, where people need to do day-to-day shopping? How can we integrate it?
