So which is right?
Secondly, does the 747 have a stick pusher as well as a stick shaker?
I would not imagine the 747 would stall that much differently from the 737 which we did full stalls straight ahead in a number of years ago. There was a noticeable buzz in the airframe as we slowed. The buzz turned into a vibration and that into a hard shaking as though "Do you really want to do this?" Plenty of natural stall warning although we were well into the shaker. Full aft stick and when it stalled, the nose fell through like a big C-150. Release back pressure, add a bit of power and away we went.

Clean, partial flaps and full dirty.. all the same. No real vices shown.
