Faster Transactions - BCH increase its block size therefore transactions can be completed at a lightning speed as compared to bitcoin. Bitcoin takes time to confirm transaction on the blockchain which makes it a big disadvantage to use it a a payment method when transacting online
Cheap transactions costs - transaction cost on BCH are far much cheaper than BTC, it cost about $0.18 per transaction so merchants wont have to incur unnecessary transaction cost as it will force then to pass the cost to end users by increasing their prices in order to meet their transaction cost.
So if you want to consider accepting cryptocurrency as payment method then Bitcoin cash is th way to go as it is cheaper and has a faster network.
