Its really a tough choice to select, but I think ETH is still king. Xrp was a short time profit coin and the foundation says more about that. But on the long run xrp can prove me wrong. But I still believe its ETH that will always win this battle cos of its function & concept.
I agree with you, Ethereum is the 2nd most used cryptocurrency after bitcoin. XRP is usually just used for quick pump & dumps. Also most crypto users won't support XRP because it is a centralized currency. I own zero ripple myself but I do own BTC and ETH. Thats not to say you won't make a profit from buying ripple but I think ethereum will perform better over the long term.
