Does anyone know if there is a difference between the two?
Any difference in the XTR and SLX BB?

They all work with each other.
Between 960 and 970... color is different for sure. Not sure about weight or quality of the bearings.
The SLX uses the same BB as the m770. And again, the color is different... I do know the m970 BB is slightly lighter.
