What is the difference between ENS and space ID?

Could you elaborate on the key differences between Ethereum Name Service (ENS) and Space ID? I'm particularly interested in understanding how they function differently, their use cases, and any potential advantages or disadvantages each might offer. ENS, as I understand, is a decentralized naming system that allows users to register human-readable names for addresses on the Ethereum blockchain. On the other hand, Space ID seems to be a domain name system for decentralized web applications. I'd like to gain a deeper insight into how these two systems vary and which one might be more suitable for different applications.
