Which is better, XRP or Solana?

Which one should I choose, XRP or Solana? I'm trying to diversify my crypto portfolio and these two seem like solid options. But I'm having a hard time deciding between them. Could you help me understand the pros and cons of each? How does XRP compare to Solana in terms of scalability, speed, and cost? Also, what about their use cases and potential for future growth? I'd really appreciate your insights on this.
