Is Cardano better than Ethereum?

I've been hearing a lot about Cardano and Ethereum, and I'm curious to know which one is superior. Could you help me understand the key differences between these two blockchain platforms? For instance, how do they compare in terms of scalability, security, and the sustainability of their networks? Also, I'm interested in their respective communities and the support they provide to developers. Is there a clear winner in these aspects, or does it depend on the specific use case? I'm leaning towards Cardano due to its focus on scalability and sustainability, but I'd like to hear your expert opinion on this matter.
