Actually it is used in some library code where no there is no knowledge of the form of the expression. For example, both dsolve and meijerint (I believe) use it.
If you do know the structure, you will have better luck applying specific functions. Also note that simplify can be slow for large expressions, so if that becomes an issue, you might want to add a flag to disable it (such as with dsolve).
