Is there a difference between waveform and truth table to represent the values of a circuit?

For example:

enter image description here

Are there particular cases where one or the other should be used?

Both can convey the same information if you only want to describe the steady state behavior of a combinatorial logic circuit.

Waveform pictures additionally can convey time-dependent behaviors (a.k.a., transient behaviors) of circuits, and they often are drawn for that purpose. Also, they could be drawn to describe changing states of simple sequential logic circuits.
