Near Earth's surface, when (Delta U^{G}=m g Delta x), it is customary to let the gravitational potential

Question:

Near Earth's surface, when $\Delta U^{G}=m g \Delta x$, it is customary to let the gravitational potential energy be zero at Earth's surface, instead of at infinite separation as we did in Eq. 13.10. Does this choice of zero yield greater or smaller values for the gravitational potential energy? By what amount?
