hmmm...Are you talking about over all threes lifetime in the gaming division or just this gen? If it's just this gen I would go with MS. They released the first HD console and were first to this gen. They have stuck with Japan even with poor sales. Released faulty hardware at the beginning of the gen(most ballsy); knowing it wasn't sound. Released Kinect; a controller free motion controls, while Sony played it safe and went with the Wiimote copy. MS has relied very heavily on Xbox Live and probably the main selling point of the consoles at this point.
Now if it's over the lifetime of each company I would go with Nintendo.
