The benefit to this is that it makes the aircraft much more maneuverable.
A common misconception. Actually it does not make it more manouvreable, it reduces the drag which increases top speed.
The impression of increased manouvrebility comes from the fact that as the C of G of an aircraft moves aft, the centre of gravity and the centre of pressure are closer together. Consequently, the size of the control input required to generate a given pitch rate reduces which leads to the impression of the aircraft becoming more pitch sensitive.
