I think that a 24MP sensor is ideal, wheter FX or DX as it gives a bit more fine detail for editing/cropping.
However if you frame accurately then 12MP is enough unless you need fine grained images printed large 50"x40" prints or more.

I would say on the physical side that a FX is bulkier and heavier than a DX body. On the same theme FX lenses are like for like heavier than DX lenses and also Nikon has a better selection of FX lenses than DX ones.
So all in all I think the FX market is better served by Nikon, this is reinforced when you look at the body releases. All the professional bodies are FX and the amateur/consumer grade ones are DX.

This FX/DX debate is a real issue as sports and wildlife photographers need long telephotos to get frame filling shots. Obviously a 300mm is fine if the subject is close by when using a FX camera but having a DX camera with the same 300mm lens fitted provides an image that is larger due to the x1.5 magnification factor of the lens on a smaller sensor area.
It is a question of more or larger heavier kit to provide the same image size on the sensor.
Depending on your needs the experience varies.
