I can not say, that new crypto is impossible to beat ethereum. But Ethereum is a strong cryptocurrency that stay on its position, which is top 5 and i think in my opinion it is a little bit hard to beat ethereum. Ethereum has so many good performances, and people think it is a stable coin.
Maybe the NEO can achieve success in the future like ETH but it is not real to beat ETH in the short term. Polkadot project that released in 2017 ICO is still best among the new projects like ETH but EOS is still my preference after the delayed release of ETH 2.0.
