When a transaction is sent with InstantSend, these masternodes immediately lock the transaction and make it irreversible. This way, the receiving party does not have to wait for the transaction and it is considered to have happened instantly.
Advantages:
Transactions locked by masternodes cannot be reversed.
It does not require any extra steps for users.
PrivateSend:

Working Principle: PrivateSend uses a method called “CoinJoin”. Transactions from multiple users are combined and mixed. This makes it impossible to track which money goes to which address.
Advantages:
Transaction details are hidden.
Transactions become more secure.
User identities are protected.
