1. Cuk converter uses L-C type filter, so peak-peak ripple current of inductors are less as compared to the Buck-Boost converter.
2.In CuK converter, when switch is closed then capacitor 'C' provides energy to the load as well as inductive filter. But when switch is open then energy stored in the filter inductor is fed back to the load. Where as in case of Buck-Boost converter, when switch is closed then source is disconnected from the load and when switch is open then energy stored in the inductor is fed back to the source.
The obvious advantage is the continous input and output currents for the CUk converter
