Really, ANY algae that grows well in a refugium is "good" algae. The point of a fuge is to grow stuff there that will take up nutrients that would otherwise be used by algae in the display. Most will prefer chaeto, caulerpa, etc, but having gha or other algae in the fuge is no different than having an algae scrubber. Heck, at one point, my fuge was covered in cyano - but zero in the display
