The answer to your quest really lies in application. Some may vary the alignments based on how they drive or if they compete the car.
For me, autocross and track events are the bulk of what the car is used. So, I like more negative camber (-1 degree) in the front and rear. Any more and my tires don't last. The toe setting is neutral and the caster is not adjustable.
