Grip the mouse with finger tips only, now try to move smoothly then suddenly change directions.
You can feel that the light mouse responds much more quickly and with less pressure than a heavier mice..
Where is the advantage.... For sniping.. Doesn't really matter..
But if you're entering... This makes all the difference... and you feel far more in control while using the light mice..
