Why the choice between quantity and sparsity, ie between extensive laser and minimal hand engraving?
Basic to all engraving is good design and layout. That is the basic part of the training course in Italy since it is the major factor in the outcome.
A well laid out design exploits the shape of the gun it decorates, and that is the clue to good work, a round action needs different layout from a sidelock and so on. A kitsch lay out with lotsa gold will not be uplifted even by the best hand work.
As for preference, I prefer no engraving or a WELL done border around naked steel.
