Just in terms of readability and maintainability I find polymorphism to be significantly worse than switch-statements. It's hard to locate all the implementations of a particular function and read through them and edit them when they aren't in one place in a single switch statement. Higher performance is merely extra icing on the cake when using switch statements over polymorphism.
