In addition setters can be misused. If updateSomeOtherStuff() will change some view this will crash.

public class MyFragment extends Fragment {
   void setData(someData){
       this.someData = someData;
       updateSomeOtherStuff()
   }
}

If one passing in a bundle it is not possible to misuse the setter and you will always know that this will be set within the lifecycle methods.
