The phasor diagrams are where the quantity (amplitude) and the angle (in time) is defined. The vectors are where the amplitude and the direction angle (in space) is defined.

Phasors (due to time dependence) are usually fourier transformed into a series of sine-waves with different frequencies. And the ones with different frequencies can not be as easily added up as the vector diagrams.

I am yet to treat (and not sure can treat) phasors having different angles in space ie a mixture of phasor and vector.
