Many people say that ETH is an old coin so that it prefers the EOS concept, this is what makes many ETH investors turn to EOS and with the current trend, of course I prefer EOS compared to Ethereum.
I will say that EOS will take some time to reach to the stage at where ethereum is right now and as we can see ETH is also doing its struggle with the passeg of time so it is possible that ETH will move more faster then EOS. In this way I will prefer ETH.
