Is Polkadot better than ETH?

I've been hearing a lot about Polkadot and Ethereum, and I'm wondering which one is the superior choice. Could you help me understand the advantages and disadvantages of both? For instance, which blockchain offers better scalability, security, and interoperability? Also, I'm interested in knowing about their respective ecosystems and the potential for future growth. Is Polkadot's cross-chain capability a significant advantage compared to ETH? Or does Ethereum's established status and wide adoption give it an edge? I'm really keen to learn more about this comparison and make an informed decision.
