Callback vs Factory in UVM

Callbacks and factory address different areas of re-usability.

Callback: Add functionality to existing logic.

Factory: Change the existing component before build, keeps environment same.

Although the callback and factory can be interchangeably used to address the same problem. Depending on the need and demand, a wise decision should be made while adopting either of the techniques as they have their own merits and demerits.
