Why choose Cardano over Ethereum?

Could you elaborate on why one might prefer Cardano over Ethereum? I'm particularly interested in understanding the advantages Cardano offers that distinguish it from Ethereum in the realm of cryptocurrency and finance. I'm aware that Cardano touts its sustainability, scalability, and decentralization, but how does this translate into practical benefits for investors and users? Additionally, how does Cardano's governance mechanism compare to Ethereum's, and what impact does this have on the platform's overall direction and development? Finally, given the rapidly evolving nature of the cryptocurrency landscape, how does Cardano ensure its competitiveness and relevance in the long term? I'm keen to hear your thoughts on these points.
