I can imagine cutting with a 1HP spindle to be akin to watching paint dry.

Both those wood router spindles are going to be far less powerful and capable than the 1 HP three phase spindle that comes with the shopbot. Wood routers are usually advertised with peak H/P numbers and are less efficient than a proper spindle.
