I have found some points.
MLOAD (MultiLoad):

- Each MultiLoad import task can do multiple data insert, update, and delete functions.
- Each MultiLoad delete task can remove large numbers of rows from a single table.
- Each MultiLoad import task can have up to 100 DML steps; 
- Load data into multiple tables. 
- Works in batch/interactive mode.


FLOAD (Fastload):
- Fastload works only on empty tables(Best for truncate and load strategy).
- Works in batch/interactive mode.

Please add/share your thoughts.

Just addition to the above answer -

Teradata Parallel Transporter (TPT) is a parallel multi-function load environment. Types of system operators in TPT are:
Export – extracts data from Teradata.
Load – loads data into an empty table similar to Teradata Fload utility.
Update – upsert, insert, delete and update operations performed in Teradata tables similar to Teradata Mload utility.
Stream – upsert,insert,delete and update operations in near real-time mode

You cannot access (Macro, Trigger, Joined index, Stored procedures, Hash index, Permanent journal) Teradata objects using TPT.
