world of difference

Complete change between

A world of difference is an enormous distinction between two things—so vast it might as well span continents.

The phrase emphasizes how dramatically things differ or have changed: There's a world of difference between knowing something and understanding it.

Often used to highlight transformation: A good night's sleep made a world of difference.
