Easy answer Z4 M.
If you thought the scream of the S52 at high revs is exhilarating, wait til you hear/feel the S54 at high revs.
While there's no denying that the tuning potential and horsepower per dollar spent of the N54, or any FI motor for that matter, is way above a naturally aspirated unit, all that extra torque and power doesn't necessarily translate into a better experience on the back road.
While low end torque and not having to rev up an engine may be preferred by some in daily driving, on the back road the linear, progressive, and predictable delivery of power and high revving nature of a naturally aspirated engine amounts to a far superior and emotional driving experience.
Couple that with the M-specific steering, suspension, LSD, and braking system out of the box and the Z4 M becomes the clear winner.
