Both coins are far from ideal. Zcash with with its early distribution system is a joke.
With their slow start and mining tax devs wanted to do something to favor investors and prevent advantage of early adopters at the same time.
But they failed to realize it will make Zcash less interesting for everyone else. And ZCL is just a copy and like all clone coins it might go down very quickly.
Do not forget that Ethereum Classic was a copycat too, and look at its success now.
Good classical versions do have capability to be successful.
ZCL will eventually be added to Poloniex and it'd be the first big success of it.
Success? What success you are talking about - Current price of Ethereum: $10.5, price of Ethereum Classic $1.31
So if price 10x less that original is a success for you then yes, I suppose Zcash Classic can repeat this as well.
