Or perhaps neither? It's conventional wisdom these days that composition often works better than inheritance.

It's even more conventional wisdom that these two things are absolutely not mutually exclusive and that it's actually recommended to use both.

By the way, "composition" is ambiguous:

- Composition of functions, which is pretty much mainstream in most popular languages today.
