Should I buy Ethereum or Cardano?

I'm really torn between investing in Ethereum and Cardano. Ethereum has been around for a while and seems to have a strong community and ecosystem, but Cardano is also making some impressive strides in terms of scalability and security. What do you think? Should I go with the tried-and-true Ethereum or take a leap of faith with Cardano? I'm looking for long-term growth and stability, but I'm also open to new and innovative projects. What would be your recommendation based on the current market trends and future potential?
