Bitcoin is Bitcoin. It stands alone.
BCH is an altcoin so we can speculate about how it might perform longterm compared to DOGE or NEO or EnjinCoin, etc.
Bitcoin Cash Works
Low Fees
Fast Transactions
Inflation Control
Core BTC Coin does not Work
Insane Fees / $20 to send $60
Insane Wait time / Weeks for transaction to complete
Maybe instead being stupid, you get smart and just fix core coin flaws instead of blaming others because you stupid.
Dogecoin , ok for quick payment, not safe to hold
Low Fees
Fast Transactions
High Inflation destroys it ability to be store of value ,Price per coin will always drop over time, Making too many too fast
