This will be a never ending debate on which one is better as long as none of them fails. For me Bitcoin Cash is not better than Bitcoin, and how can a fork coin be better than Bitcoin if it has no uses? while it is still dependent on Bitcoin's growth just like other altcoins. Maybe BCH can handle more transactions per day compared to BTC but Bitcoin developers already have a lot of scaling solutions (Segwit, Lightning Network, Schnorr Signature) that will prove that big block size is not the solution. BCH is useless just like other fork coins. So why some people still believe that BCH is better? It is either they just want to see Bitcoin fail and for people to choose BCH because they think it is better or they are supporters of Roger Ver lol.
