Bitcoin currently can handle up to 10 transactions per second and Bitcoin Cash is 213 transactions per second. Transactions per second are mainly determined by blockchain blocksize. Since Bitcoin Cash is larger than 32MB (compared to Bitcoin from 1 to 4MB), BCH can handle more transactions at a lower cost than BTC.
Maybe that is the reality, cause i don't have any idea with difference between the two coins in doing transaction method. However, bitcoin cash is something above with the feature but it cannot surpass the current value of today's market trends.
