> I think this is something of a debate on "is it good to get some exercise?" vs "is walking or swimming or weight lifting a better exercise?"

This is an astute comparison, and I think you're completely right. One who devotes time and effort into practice (nearly any practice) of handwriting will improve.

However I would liken it more to something such as: "will Olympic weightlifting make me a better soccer player than sprinting, ball control, and team coordination drills will?". It's not a generic A or B, as we're trying to achieve an intended result.

More aptly, "given I want to achieve C, is A or B a better approach".
