In my opinion the Konis are worth it. Improved handling and huge improvement in the way the car handles potholes and poor road surfaces. The "Dual Personaility" nature of the FSDs is a perfect match for the rather poorly sorted out, overly harsh 3 Series Sport suspension.
I have no experience with the Bilsteins but I know they make a quality product.
