What's better, XRP or Cardano?

Excuse me, as a cryptocurrency aficionado, I'm torn between two promising projects: XRP and Cardano. Could you please elaborate on which one you would recommend? I'm particularly interested in their scalability, security features, and potential for long-term growth. Also, how do they fare in terms of community support and adoption? It's quite a dilemma for me to choose between these two, so your insights would be greatly appreciated.
