higher inductance
Usually the larger inductance reduces the ripple current which yields 2 benefits:
1) Less capacitance is needed to keep the ripple voltage suitably low.
2) The transition from continuous to discontinuous operation will happen at a lower output current, increasing the power span, at which the converter needs no change in duty cycle to maintain the output voltage (well, almost no change anyway).
On the other hand, a larger inductance will negatively affect transient performance, because it becomes increasingly difficult to change the inductor current quickly as the inductance goes up (to accommodate a change in line or load).
