I specifically mentioned the main engines. And we can't really compare with the F9 when, once again, it has never been reflown. A lot more of the Shuttle was intended to be reusable than ended up being the case - who's to say how that will play out for the F9?
The shuttle main engines required a lot of maintenance and inspection after each flight. That's to be expected at the start of a program, but they never got away from that.
