The Shaper Origin has you move the machine, and it makes corrections using machine vision to track its position. It will give you more accuracy than a Maslow; but at a much greater cost and more attention.
A jig saw does not make as clean cuts as a router, and you need to have the workpiece suspend so the blade can go through the work. With a router, you can just have a spoilboard underneath.
I really don't understand the market for the shaper. Even the youtubers that get paid to shill them don't seem to have a compelling reason to be using them.
