Create/destroy 3d object on coded button.

I am trying to make a button or a selection box on a GUI that creates or destroys a 3d object (or series of objects) I have a male and female model and simply want to switch between the two quickly. Should i just lode another level with the same scripts running or am i correct on thinking its better to create and destroy the objects via a button ?

The best approach would probably be to put them both in 1 scene and switch between them using gameObject.SetActive(true/false). It’s a lot faster than loading scenes or instantiating objects.
