Well, it depends what kind of Pokemon you want, either defensive or offensive. If you want offensive, you should choose Noctowl and in this case what is super effective to both of them don't matter because they are the same thing. Anyway if you want defensive, then I recommend Togetic. Although I would personally choose Noctowl because it has pretty good defense itself but not as good as Togetic. So Noctowl has a lot of health and attack while Togetic has pretty good defense.
Hope this helps!!:D
