The differences will be in how the internal Digic I,II,III, or IV process handles the tones of the recorded colors. The black and white output is a simple desaturation of the color leaving only grayscale. The Nikon D300 may do more but I imagine that it is more a function of a boosted mid tone curve than a special black & white conversion. Nikon has a tendency to boost the mid tones of an image to create a perception of higher dynamic range. Canon has a tendency to leave it alone. Black and whites out of a Canon camera will probably look more dark gray rather than mid tone boosted black and white. This is a simple thing to emulate in post processing, especially if you shoot Canon RAW.
