I've come across several instances where someone has stated that white is the best choice to color balance in ACR. Something about how the files are encoded. Grey will work, but its not as accurate as white. Is this true? They point out that ACR only has a white sample tool, while PS has three grey, white, and black.
Thanks

I may be misunderstanding you, but the eyedropper tool in ACR won't work with white or anything too close to it. You need to sample something that you want to be a neutral gray.

Are the PS tools you refer to the ones in the Levels command window? I don't think they work quite the same way as a white balance eye dropper, though they can amount to more or less the same thing on certain images.
