The EOS blockchain has some problems and one of the major ones is that it is not even fully Decentralised and this has made some experts to say that it isn't even really a genuine blockchain project because of it's partly centralised model.
Ethereum has become the third in cryptocurrency world. Telling the truth it has become a surprise for me, an unexpected result of last events on the market. I don't think that Ripple is worth to be the second currency but my voice of course means nothing.
Ethereum will survive and EOS. But Ethereum is a leader.
