Which is better Cardano or XRP?

I'm new to the world of cryptocurrencies and I'm trying to decide between investing in Cardano and XRP. Could you please help me understand which one is a better choice? I've heard about Cardano's focus on scalability and sustainability, while XRP is praised for its speed and low transaction fees. Which factors should I consider when making this decision? Also, are there any other cryptocurrencies that you would recommend looking into? Thank you for your time and expertise.
