Example:

Slower monitors like 30hz and 60hz let you see less frames of the game, so it is harder to know when or not when to press on the screen/spacebar/up arrow or click.

Faster monitors like 120hz and 144hz are 2-4 times faster depending on which monitor you have originally and which one you change to, so it is easier fly straighter.
