What is actually the most decentralised Altcoin?

Really! While the community is busy evaluating transactions per second, why aren’t we evaluating decentralisation metrics?

So. What is actually the most decentralised Altcoin? And please, include some information in your response to demonstrate how you arrived to this conclusion.

Please don’t say ETH 2.0! I get it, but it’s not in the market today, then it doesn’t have a seat on this table. Just how Cardano doesn’t have a seat on the dapps table (yet).
