Accelerating something macroscopic to hundreds or thousands of km/s (i.e. the speeds you can achieve with nuclear pulse propulsion) on a ramp that fits on the moon seems quite difficult to me.
Mass drivers don't need to be a linear ramp, portions can be circular
It would work better for smaller, unmanned craft, especially when you consider g force limitations
NPP is only theoretical, and still has major problems such as finding a material that can withstand a nuclear detonation at point blank range. Mass drivers have been proven to work, albeit at a smaller scale
