According to me if you want invest then you should invest with eth, Because eth is very promising ans stable coin.
And on the other hand ripple is quite imbalace that's why i think you should invest with eth.
For me its better if enthereum to invest because some of investors enthereum is use to invest because enthereum is the second of bitcoin and the price of enthereum is good for investing.ethereum is good for longterm investment because the price of it is moving and i think in the coming years ethereum will expensive pricing and you can get it a good profit.
Ripple is not even decentralized and I never invest my limited money in ripple company. They're against crypto spirit honestly. I would like to consider my investment in ethereum instead.
