When you are considering an object falling in the atmosphere the only determinate when it comes to how fast an object will fall is the area of the object and therefore the drag(resistance) it will produce, mass does not come into it.
Yep, mass does not come into it. Which is why a helium-filled balloon falls to the ground in exactly the same manner as the same ballon filled with water, as everyday experience confirms.
This thread is a telling example of how confused educated people can get - on firm ground.
