For normal driving, Audi quattro with the longitudinal setup and torsen is
probably the most seamless and one of the most effective.

BMW xDrive is also very good.

Haldex systems are theoretically very good, but they tend to be 100F/0R
until slippage occurs, not a "fun" torque split.

Nissan/Infiniti ATTESA-ETS is also very good.

Out of the current AWD cars out there:

BMW 535xi Touring 6-speed manual gearbox
MBZ ML320 Bluetec
Audi A4 2.0T Avant B8 chassis but only when DSG is released (no manuals for
US)

used B7 Audi RS4 (droool)
