That's like asking if you should marry a tall gal or a short one - it depends on what
you want.
If you are more concerned about the amenities, the Touring is probably the best choice. If you are more concerned with performance, the Sport. Maybe you should start looking for a Sport + Touring.
I have a Touring and like it. For the way I drive (spirited driving around town) the Sport package would be overkill.
