I think i gonna vote for EOS. Although it place in 5th position at coinmarketcap, but it have big potential to compared with Ethereum. Beside EOS have smart contract like ethereum, EOS also offer a promised feature that believed can beat ethereum. That's elimination of transaction fees which is become ethereum's weakness. The price of EOS also have a great growth after it launched. But still i'm not going to say EOS can replace Ethereum for now. It just have potential to stand beside ethereum than another coin. I would prefer ethereum than another for my self.
