Objects/classes work best for datastructures (IMO).

Outside that usecase, I think polymorphism via inheritance is generally a mistake.

Programs manipulate data and datastructures organize that data in a way that's algorithmically efficient.

The main issue with OOP is that without a very clear abstraction, it can be almost impossible to reason about code as you end up needing to know too much about the hierarchy of code to correctly understand what will happen next. As it turns out, most programmers are pretty bad at managing that abstraction boundary.
