I agree with your comparison of fit to handwork, but I do no agree that fit is the most important factor.
The most important factors, in my opinion, are the basic design and aesthetics of a coat. Those compose the starting point, preferably in the context of a whole look.
Then, those aesthetics need to be applied individually to a human body using the best techniques of construction and fit that are possible at a price point.
Those techniques, at higher price points, will include human hands cutting, sewing, and knowledgably (both technically and aesthetically) assembling the garment and then fitting it to a real person at various stages of construction where adaptations are most successfully done.
Hand-sewing is only one element, and if used in a context that does not take advantage of its capabilities (which really is in a full bespoke garment, or something close to it, executed by someone trained in a bespoke environment) some, or even a lot, of the hand-sewing achieves only superfluous decoration at best, or devolves into a marketing gimmick at worst.
