What kind of shotgun?
How tall is your neck?
Traditional stock for sure.
If you have a shorter neck, a Mossberg, Winchester, Browning, FN stock out of the box will likely "fit" pretty well, even before shims. If you have a longer neck (like me,) a Remington, Beretta, Benelli stock will fit your body better, as they typically have more drop from the receiver, and an angled comb.
I have a giraffe neck, and these Remington/Beretta/Benelli stock dimensions fit me very well.
Since the rear sight on a shotgun is actually your cheek weld, having a proper & comfortable fit is paramount. When speed is priority, this matters.
To answer your question, traditional stock, but make sure it fits you well.
