In my opinion, XRP is a better investment compared to ADA. This can be proven by XRP competing nicely with ETH for the 2nd and 3rd position in terms of market capitalization. Also, XRP is backed up by the Ripple platform that can be very useful in banking institutions.
maybe if for the long term I think it's very true but if for fast trading I think XRP and ADA are good because according to my monitoring both of them have pretty good graphics.
so if I personally would also prefer XRP because it's good for trade and also long-term investment.
but it all depends on the taste of each person because sometimes other people's opinions are different.
