In a vacuum, they always land at the same time.
In air, it's not so much the weight but the air resistance.
If the shape and density are about the same, then the difference in weight doesn't make any difference.
Assuming that each object is held with its center of gravity at the same height, and that each is dropped cleanly, with no rotation induced, the one whose lowest part is closest to the ground when dropped will hit first.
Galileo carried out his first experiment on gravity by dropping weights from the Leaning Tower of Pisa in Italy. This famous experiment is said to have demonstrated that objects of different masses fall at the same rate due to gravity.
None of these matter. With no air resistance, they all hit the ground at the same time.
In the absence of air resistance, objects of different masses will land at the same time when dropped from the same height. This is due to the acceleration due to gravity being constant for all objects near the surface of the Earth.
There were two Until Galileo's experiment, it was widely believed that large objects fell to Earth faster than small ones. That is, it was thought that if two objects of different sizes were dropped from the same height, the larger one would strike the ground first. Galileo showed that not to be the case. But his experiment was extraordinary for another reason. Galileo discredited another Aristotlian idea: that natural phenomena could be explained solely via analysis. Up until Galileo's time, the scientific method had yet to be developed; experimentation was largely unheard of. Proving or disproving a hypothesis via experimentation was not done. Aristotle and his peers believed that natural laws were discovered through discussion and argumentation, and the philosopher who articulated and defended his theories most persuasively was credited with their discovery. Validation through experimentation was not required.He dropped two cannonballs of different masses from the tower and watched them hit the ground at the same time, disproving Aristotle's theory that mass affects the gravity in acted on an object. He proving that mass doesn't matter but air resistance does. But, it was never proved the experiment was done at the leaning tower of Pisa.Debates had started up on one of aristoles laws of nature, that heavier objects fell faster than lighter objects. Galileo wanted to try. He needed to be able to drop the weights from a tall height. The perfect building was The leaning tower of Pisa that was 54 metres tall. He dropped the 2 weights and found out that aristole was wrong. Because the two weights fell at the same time.
Both weights will hit the ground at the same time, as gravity accelerates all objects at the same rate regardless of their mass. This is known as the principle of equivalence.

"Galileo was the first to really discredit Aristotle's laws. He did this by postulating that heavier objects would hit the ground at the same time as lighter objects, when dropped from the same height. He proved this with a famous demonstration where he dropped two balls of different weights from the leaning tower of Pisa. The balls hit the ground at the same time. Galileo also came up with the idea of inertia. Rather than take Aristotle's view that and object must have a force acting on it to keep moving, Galileo said that an object would move continuously in a straight line as long as no outside forces acted on it."
If two objects of the same weight are dropped from the same height in a vacuum (without air resistance), they will land at the same time. This is known as the principle of equivalence in physics put forth by Galileo.

The hammer would hit the floor first because it is more dense than the feather. When objects are dropped in a vacuum where air resistance is eliminated, gravity pulls them down with the same acceleration regardless of their mass or density.
