Ethereum as you say is way better to consider as an investment if you compared the Ripple by itself.
I agree, especially with how Ethereum is transitioning to POS which will allow people to generate passive income, which isn't something you can do with XRP, neither do I believe that XRP will be adopted by financial institutions.
Ethereum has much more liquidity too, which means that it's much easier to cash our or enter for large players, which can't really be said about XRP.... its market cap is very deceiving.
Another thing is that Ripple the company has been selling a lot of its XRP reserves, which as we can see didn't bode well for the price.... they singlehandedly made sure that it went lower and lower due to the constant selling pressure.
