The heavier airplane if balanced correctly...will not be able to...climb as well.....be a little more sluggish on the controls.......will dive faster...on the flair or on approach the airplane will sink quicker.....it will stall sooner.....probably penetrate the wind better....
the lighter airplane if balanced correctly.....will climb quicker......control response will be normal or require less movement for the same result....on the flair or approach the airplane will tend to float...will burn less fuel.....the wind will have more of an effect......
