I would say that running in hills (involuntary pulse&glide) is better than pulse & glide on flat roads at the same average speed. The reason is that you lose less energy to aerodynamic drag.
On flat roads, with p&g, you have to exceed average speed half the distance, which hurts drag exponentially. In hills, you can keep a more constant speed (if the decline is right). If the decline is to steep and the speed gets too high, the advantage is lost (you won't get as far horisontally for your built up potential energy).
