a touch more active and its transitions happen quicker than the Subaru's

For those of you reading this, don't take this to mean quicker through the corners ;)

Take the example of toe in vs toe out: toe in will feel "quicker", as on turn in you'll have an initially higher gain in yaw moment control (hence higher yaw acceleration), yet your system will reach equilibrium slower than if you were to gradually work your way up your force curve with an initially lower slip angle (toe out). Steady state dominates time wise, and setting up that steady state (hence a good turn in) is what's important.

Has Toyota simply tuned the transient roll response to be more "fun" for the guy working for the car magazine? ...probably better for sales considering the market for this car.
