Its important to add that with Monero all transactions are encrypted with ring signatures and are therefore the whole blockchain is truly anonymous.
With Zcash or DASH you have unencrypted/public (fast, cheap) and encrypted (expensive) transactions. This system with low and high tx fees leads sadly therefore to that most people use unencrypted transactions, which weakens the integrity of the whole blockchain.
You dont have that with Monero, that really is the key advantage of it.
