Usually if you have the choicie, then probably that composition is better as it will better separate what main and secondary object do.

Main object will not be polluted by functions that would otherwise be inherited but are of no use to external user of the main object.

Typically you want to use inheritance only for IS-A relationship or if you have to override virtual functions.
