Circuit boards (if intelegently designed) enable optimum placement of components with minimal wire runs between them. And, it avoids the need for wire "dressing", which always was something of an art. Depending on how many of the circuits you will manufacture, circuit boards may or may not be less expensive to produce. The use of "point-to-point" wiring may reflect the fact that few of the units are produced, and the supposed benefits cited as a cover-up.
