Tezos is interesting, upgrades happen without forks and are voted on-the-chain. It’s developer-friendly and seeing slow adoption with some governments. Allegedly France’s C3N uses it and Reno is testing it with NFTs.
Bonus points for it being overseen by a Swiss non-profit, they fund development efforts and encourage adoption.
Who knows what the end result it, but I think the ideas there make it favorable compared to BTC and ETH. Not to mention lower transaction fees :).
