I prefer Ethereum, I think Ethereum prices are more stable suitable for long-term investment, Ethereum development is also good from year to year increasing, so I believe the future of Ethereum is brighter than EOS. Also, etherums fundamentals are great and this would definitely drive the price higher
I also prefer Ethereum above all kind of altcoin exists because aside from the great technology behind it the quality and the potential of this crypto is already proved and I bet that everyone has also the same outlooks towards this coin. However, like any other coin Ethereum also experienced having a price decrease.
