What is the difference between XRP and XLM?

Could you please explain the key differences between XRP and XLM? I'm interested in understanding how these two cryptocurrencies differ in terms of their functionality, purpose, and the networks they operate on. Could you elaborate on the unique features of each and maybe even discuss their potential use cases and advantages? It would be helpful if you could also compare their market positions and performance trends. Thank you for your assistance in clarifying this topic for me.
