setParent or addChild

I would like to know if there is any difference/advantage between attaching a scene node to a camera using node->setParent(camera); or camera->addChild(node), besides the order of declarations?

I'm testing both with the same results.

They have the same effect. setParent() can be used to set the parent to NULL if you want to remove a node from the scene graph temporarily. It calls addChild() if the parent you specified is a valid pointer, so setParent() is a tiny bit more expensive.
