There are tradeoffs for sure. If it helps, I never once ever used the slider wagon with the router in all the years it was attached to the saw. Unlike with an integrated setup like a saw/shaper, the "business end" of the router table was just too far away from the wagon to make it practical for very many things and it also meant more leaning forward sometimes when running certain things. OTOH, it was great when I need to do edges with things like roundovers on really big things because there was that big, flippin' saw supporting a whole bunch of "whatever" during the task. I've kept the router separate this time around for the new shop.
