All Technique are perfect.But when its need for Compile Time polymorphism then function/ Operator Overloading are used while when its run time polymorphism ,then Virtual function is used...the fact is that, as a Pure Virtual funcation ( Used for run time polymorphism) provide a foundation & concept of abstract Classes, makes it better than both above.

Polymorphism in C++ is broadly classified as :
1. Compile time Polymorphism eg. Operator/Funtion Overloading
2. Run time polymorphism eg. Virtual functions.

Compile time polymorphism is compartively faster that run time polymorphism. But Run time polymorphism provides more flexibility.

Thus, using either of two depends upon your requirement.

For Compile time polymorphism, Function/Operator overloading are good example

For Run time polymorphism, Virtual Function is good example.
