What is the difference between cosmos and Polkadot?

Could you elaborate on the key distinctions between Cosmos and Polkadot? I'm particularly interested in understanding how their architectures, functionalities, and approaches to interoperability differ. Could you provide examples or clarify any technical nuances that might help me grasp the nuances of these two blockchain ecosystems? Additionally, I'm also curious about the community support and adoption rates for each platform. How does each fare in terms of attracting developers, investors, and users? I'm eager to learn more about these projects and how they fit into the broader cryptocurrency and finance landscape.
