Welcome to the Router Forum! My own thinking would be cost. The unit (shaper) is more expensive, if it is a true shaper. The cutters are usually more expensive. In the long tun, the router does many things just as good, or better. The router can be held and moved quite easily. with the table, it is still more mobile, considering on the model of table. The only thing a router doesn't do is run back wards, and that doesn't seem to be a big minus. For home use, the router is almost always better suited. Now if you have more money than you know what to spend it on, Then the shaper is a nice tool for the heavy work. I hope that this helps. Thanks for asking. the forum will give you assistance with questions if we can.
