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 haven't seen anything solid development for BCH as compared to ETH platform, where they are in continuous improvement of their technology. So I don't think BCH will win on this area. Are BCH developers transparent with their plans? In my opinion, Eth dev team is stronger than BCH, and they have the capability to deliver results as compared to BCH team.
How will you see it if you haven't tried to even google it? BCH has more than 10 different wallet implementations and all of them are working on different features - Schnorr signatures, preconsensus, oracles.
Not to mention ecosystem participants such as Satoshi Dice and OpenBazaar.
Ethereum is developer-based so it needs more developers to be relevant, BCH needs to be cash and it has more than enough devs to fill in the ranks. Ethereum has interesting proposals with Plasma and PoS but they are also more risky - and if they work out, quite frankly ETH will overtake not only BCH but BTC as well. Or it will fail miserably, time will tell.
