Why is Cosmos so good?

Could you please explain to me what makes Cosmos stand out? I've heard a lot about its potential but I'm still not entirely clear on its unique selling points. Is it the scalability of its blockchain technology? Or perhaps the interoperability it offers with other blockchains? Also, I've heard about its governance model, but how does it work in practice? I'm curious to know more about its ecosystem and how it's shaping the future of finance and cryptocurrency.
