Differentiate between Transaction code SE01, SE09, and SE10 in SAP ECC system?

In early sap version, SE09 and SE10 perform different functions as below:

  • SE09 was widely used in workbench/development of transports.
  • SE10 was widely used in customizing transports.

In newer version now, both the Transactions SE09 and SE10 perform the same function as shown in below snapshot.

In addition, SE01 is an extension combining SE09 and SE10 functions and adding lot other functions as shown in below snapshot:
