What is the difference between the Audi A8's Quattro and Quattro Sport differentials?

I am considering purchasing an Audi A8 and I am confused about the different options for the differentials. Can you explain what the differences are and which one would be best for my usage?

The Quattro differential is the standard option for the Audi A8 and utilizes a torque-sensing center differential to distribute power between the front and rear wheels. The Quattro Sport differential, on the other hand, utilizes a rear sport differential that can actively distribute torque between the rear wheels for improved handling and performance on corners.
