BCH is nothing but a pump and dump coin and forked from BTC, nothing huge difference. On the other hand, ETH was totally something innovative idea for that time. At some point, BCH will no longer be on top 10 even but ETH will be there for sure.
I totally agree with your opinion. Bitcoin cash is nothing comparing with Ethereum. Though BCH has taken as a payment method in some shops but that will not make a big deal. Ethereum contract system still seems revolutionary in the crypto market. Without Ethereum I can't think about the altcoin market. So, There is no competition between BCH and ETH! If there has then I would say ETH is a forever winner here!
