Four chapters of Bavli M'nachos (chapters 7–10 in the Bavli's order) have two versions of Rashi printed alongside in the standard edition. Toward the top of the page is Rashi printed in regular Rashi script. Toward the bottom is a commentary labeled "manuscript Rashi" and printed in smaller type. At the beginning of the "manuscript Rashi" commentary is a note inserted by the publisher to the effect that the Shita M'kubetzes had said that the other commentary was not Rashi at all and had found a manuscript copy of the "manuscript Rashi" version.
Which version is typically/traditionally studied when learning those chapters?
