Performance has more to do with the detail geometry of each set up. For instance, a lot of double wishbone setups are designed with shorter top arms, this basically allows the outside tyre to remain vertical in cornering. Problem is that in road cars, most people think they know better than the engineers and lower teh car 3inches and automatically put the tyre in a bad part of the camber curve, seriously reducing tyre grip, especially under brakes. The macpherson strut is less susceptable to this, so a modified MS would perform better than a DW setup.
A lot has to do with packaging. Try using double wishbones on the front of a FWD car. There is barely any room in there. The same thing goes for putting V8's in double wishbone setups, The exhaust comes out where the upper wishbone sits. In most cases this can be worked around though.
For a passenger type car, the MS is a cheap and easy thing, but try packaging that on the front of an F1 car.
The old valiant that I have has a neat setup, having double wishbones with a torsion bar spring acting as the lower hinge point. Nice and compact, save for the damper.
Performance wise, the DW can be made to work better but in a mass produced car like the soarer, changing ride height significantly will rarely help the handling. A better option us to use a "dropped Spindle" which is basically a new upright with the stub axle a little higher than the standard location. That way the car is lower but the suspension geometry remains as per the manufacturers design.
Man I can dribble, I think I will stop typing now.
