Why is ENS better than DNS?

Could you please elaborate on why the Ethereum Name Service (ENS) is considered superior to the Domain Name System (DNS)? What are the key advantages that ENS offers that DNS lacks? How does ENS enhance the functionality and usability of blockchain-based applications? Is it the decentralized nature of ENS that makes it more appealing, or are there other factors at play? Would you also mind discussing the potential challenges or limitations of ENS compared to DNS?
