I think Ethereum will still be the best. Although Neo is a good altcoin and is trusted by many people, Etherum still outperforms the number of daily transactions. This shows that Etherum is much better than Neo.
I think you should compare ETH vs BTC is better. It's a question that makes a lot of people confused and really makes people fascinated. Although the ETH cost is 10 times more expensive than BTC, most of the altcoin used in ICO projects is ETH.
