The one in the "Edit Size" pop out menu is the more accurate one. The one that is shown on top level UI is an approximation based off of the display mesh. Calculating the accurate tight bounding box of a solid can be a potentially time consuming operation and the top level UI changes with every selection.

When you pop out the menu it will do the more detailed and accurate (and slower) calculation at that time.
