We can use precise transfer, but the exact value of each drop so it is better to use significant as it may used in fractions.

Precise transfer is used for transferring exact amount. For eg: if you want to take amount of any solid or volume of any liquid to transfer.

Significant transfer is especially helpful in titrations where you need to transfer aliquots near the end point to get the exact end point. This is limited to two places of decimal.
