How Match decides on luminances has always been a bit of a mystery to me; but 
I don't give advice on competing products, it would not be fair to them. 

Globally: If you use the laptop and the desktop side by side, and both will 
reach the luminance you desire, set them both the same. If your laptop wanders 
the globe, and gets used in uncontrolled environments (like mine) set it 
nearly as high as it will go... and dim it on those rare occasions when you are in 
reasonable lighting. This violates a couple theoretical principles, but is a 
better all-round solution than anything else I've tried, and is quite 
reasonable in practice.
