If you have the room for the shaper and the room to use it, I vote shaper.
I hardly use my routers since I've had the shaper. You can do more with it and put more pressure on it then you could ever put on a router table; the shaper does not move. Especially when working gunnels, although I still use a router on some gunnel work. Because it is so stable and you can go real small or real big with bits, you can get things done faster and more accurately.
They are the most dangerous tool after a radial arm saw, but they do have safety devices that can be used without much interference.
My 2 cents,
