Is Ethereum 2.0 better than Cardano?

I've been following the cryptocurrency space closely, and I'm curious to know: is Ethereum 2.0 truly better than Cardano? Both projects aim to solve scalability issues and improve transaction speeds, but they take different approaches. Ethereum 2.0 promises to transition from a proof-of-work to a proof-of-stake consensus mechanism, which could significantly reduce energy consumption and increase efficiency. On the other hand, Cardano boasts of its peer-reviewed smart contract platform, built on rigorous academic research. Which one do you think has the edge in terms of performance, scalability, and security? And what about their respective communities and ecosystems?
