or doesn't it?

In the last few years there's been a large composition control and stability management used in vehicles to kerb adverse chassis reactions to driver driver input. To me it looks like it can hide or eliminate bad chassis setup and hence can only be discovered once it's switched off. I've noticed that some manufactures (Nissan with the FM platform i.e. 350Z) has limited the obtrusiveness (from I can gather has a over steer bias and easily readable chassis), whereas Mitsubishi (with its Lancer Evo) has gone the whole hog and allows the car to workout the best route (depending on driver input) but rewards the driver with a false achievement (correct me if I'm wrong).

There's a number of members of the board that have driven different types of performance cars, what is your opinion? Rather have the TC/SM off or on? Which cars have you found that when these devices are off the characteristics of the car changes completely.
