Depends what you're looking for from a wash really.
For me, I try to be as gentle as possible and not scratch the car as it's quite well polished, that means the less dirt on the car when I start the hand wash, the better. For that purpose snow foam or some other pre rinse is essential, snow foam trends to be popular as it clings to the car well and looks cool! This is the same reason I have a tank of filtered water so I can leave the car to dry and not have to worry about water spots.
If your car is already covered in swirl marks then there's absolutely no point.
