Intersects() vs OnTriggerEnter2D performance

Hi. I am making a 2D game where I need to use triggers. However, I am unsure which method is best to use.

Method 1:

 if (myTransform.renderer.bounds.Intersects(targetTransform.renderer.bounds))
 {}

Method 2:

 void OnTriggerEnter2D(Collider2D other)
 {
     if (other.gameObject.tag == "Target")
     {}
 }

The latter method will be used with to detect collision between polygon2D and box2D/circle2D colliders. Can someone tell me, which method is the best to use?
