I believe both are good and surviving cryptocurrencies in the market, But if we look at the recent status, the Bitcoin cash is not that hot compared to Ethereum in a logical way if I am an investor I will go for Ethereum in the sense that I can make a decent profit out of it, But if I am only an ordinary user, I think Ethereum is not good for me because of its expensive gas fee. thas why I'll go for other choices probably and not stick to Ethereum and Bitcoin Cash because both coins have a voracious("like always hungry") gas requirement.
