All any of these currencies are speculative investments right now. Unfortunately there's really nothing protecting the value of the assets because there are no tangible assets. Bitcoin cash, bitcoin, ethereum, every single coin out there suffers from the same drawbacks. Therefore, it is ridiculous to say one will perform better than another when you are at the mercy of a market which is irrational. Once there are cryptocurrencies which actually function as a CURRENCY, and are not used as deflationary stores of value, many mainstreamers will begin to have more confidence in this field.
