BA/BF disadvantages:
Fly by wire throttle (damn infuriating to me, and a deal breaker)
Heavier
Hard Plastics interior
Unnecessarily heavy steering
IRS
XT/Futura look very, very plain and rather dated
BA advantages:
More accepted looks, especially interior
Nice looking cars in XR/BFII/Ghia guise
Far more refined ride and seating
ICC is cool
