In addition $0\\nu\\beta\\beta$ allows to determine the absolute scale of the neutrino masses. This is not possible with neutrino oscillations. To determine the neutrino masses one must assume, that the light Majorana neutrino exchange is the leading mechanism for $0\\nu\\beta\\beta$ and that the matrix element of this transition can ba calculated reliably.
