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 myself.
Ethereum popularity is due to the ERC20 tokens so everyone can create their own tokens using various ICO projects.
But the popularity is beginning to fade when there is a new generation of blockchain like Cardano and EOS and both coins both have the chance to become the next popular coin although it can not beat the dominance of bitcoin.
