Hey Sean,
you can’t compare the power rating of the Makita router to the rated spindle power. If the Makita draws 6.5 A @ 120 V = 0.78 kVA, that is the electrical input power. According to IEC 60034-1, the rated output of a motor has to be the mechanical power available at the shaft, NOT the electrical power it draws. That current is higher. If you take the electrical power of the Makita router and take into account that a universal motor has an even worse efficiency compared to a spindle, you can expect that the mechanical power of the Makita is well below 0.5 kW. Unfortunately they don’t provide the data, they just mention the electrical input power 
Also the motor characteristic strongly differ between the two (as compared here), so the watts alone don’t really help.
