For me ethereum is better because you can make a lot lf profit to ethereum, because for once bitcoin die the next bitcoin will be ethereum and most of us believe that. Neo is a good coin but ethereum is choice to me that give me high profit in the future. You can make a research so you can know what is better to invest maybe ethereum or neo. But if you have large capital better to buy this coin so you can make more profit.
Being better is not related to the profit or economical aspect, I wanna point out. It's all about your technology that makes something even easier than anything. And ethereum is exactly doing this, not neo.
