Why is Tezos so good?

Could you please explain to me why Tezos is so highly regarded? I'm really curious about its unique features and what makes it stand out in the world of cryptocurrency. Is it its innovative self-amending protocol? Or perhaps its focus on governance and community engagement? I'm also interested in how its on-chain governance system works and how it ensures the long-term sustainability of the network. Could you elaborate on these points, and perhaps also mention any other aspects that contribute to Tezos' excellence?
