Is Polkadot better than XRP?

I've been following the crypto space quite closely, and I've noticed that Polkadot and XRP are both gaining significant attention. Could you please elaborate on the key differences between these two projects? Is Polkadot really superior to XRP in terms of scalability, interoperability, or any other important aspect? I'm particularly interested in understanding how their respective technologies work and how they might impact the broader cryptocurrency ecosystem in the future. Also, I'd like to know which one of these projects has more potential for growth and adoption. Your insights would be greatly appreciated!
