Not really , Bitcoin Cash has the Onchain Transaction Capacity needed, and using exchanges for offchain transaction gives it Unlimited Transactions capabilities.
It's scaling is unlimited using exchanges ,
so why would any of the other pretenders be needed , they will wither and die as their is really no reason for those segwit coins mutation to exist.
Bitcoin Cash can handle it all.

Then we are back where it started and all your eggs are in one basket. If BCH has a catastrophic flaw that becomes exposed after BCS 'withers and dies' then we are all fucked and the cryptocurrency world comes tumbling down. It isn't a popular view, but I am in favor of multiple successful branches of Bitcoin.
Also not forgetting ViaBTC wants rootstock on BCH (Bitmain in a a huge financial investor in RSK and a huge supporter of BCH)

And no matter how much you like it or not if its decided to implement and with ViaBTC and most likely bitmain holding over 90% of the hashing power you dont get a say
