The main advantage of a non-sync gap is that the break-rate can be
adjusted over a wide range simply by varying the motor speed.  By
varying the break-rate, you vary the input power to the coil.  So the
gap is more versatile.

Sync-gaps are best used at a 120 BPS break-rate where they can
provide smooth and repeatable resonant charging conditions
compared with a non-sync gap.  Sync gaps can be used at higher
break-rates...but offer little if any advantage.

Sync-gaps are particularly useful for neon transformer powered systems
in which steady firing conditions help to prevent transformer damage.
