Aside from personal preferences; the reason we default to ‘Satin’ finish on the neck is because it presents less resistance to your moving hand. On a magnified scale you would observe that the satin surface is irregular and has less contact surface to overcome, A gloss surface is smooth and presents more contact surface to slide over. Think of pushing a clean finger across a sandblasted glass surface vs. a squeaky clean window.
That’s the physics, regardless of opinion. The market challenge is that Crows and Humans are attracted to shiny things and find them more desirable; thus the bias towards Gloss necks and the reason we offer them as an option..
