Compare position of 2 gameobjects

Beelzeboss

Hey I was wondering if anybody can help I am trying to find a way to compare the position of 2 rigidbodys and when one object is directly above the other destroy the one underneath. I could use hitboxes but with having multiple instantiated objects I think comparing the positions may be the better way to go.

Something like this?

float tolerance = 0.01;
if	(
		(Mathf.Abs(lowerTransform.position.x - upperTransform.position.x) < tolerance) &&
		(Mathf.Abs(lowerTransform.position.z - upperTransform.position.z) < tolerance)
	) {
		Destroy(lowerTransform.gameObject);
	}
