Is XRP better than XLM?

I'm curious to understand the comparison between two prominent cryptocurrencies - XRP and XLM. Could you elaborate on the key differences between them? Is XRP superior to XLM in terms of transaction speed, scalability, or cost-efficiency? Also, how do their respective ecosystems and use cases compare? Additionally, considering the volatile nature of the crypto market, which one offers more stability and potential for growth in the long run? I'm interested in hearing your thoughts on this matter.
