Actually kind of true, although i got 3 pair of adjustable shocks in my fleet, i only adjust them once or twice during initial setup. A good shock will satisfy any kinds of roads to a certain degree while providing certain degree of improved handling and comfort. Adjustable shock is good when you need to lower your car to a height that you like, as for damper rate, you rarely mess with it. At least that's my usage so far.
If i have another choice, i would go with OEM shaped shock with sport spring and call it a day. Adjustable for street car is somehow under use.
