Pumping the cavity should be cheaper - as its faster to lay blocks without insulation boards and the pumped bead is very cheap. Wheather its more affective is a matter of opinion.

This is fine for a detached garage.
IMO insulation boards have advantages over pumped bead. Lots of threads on the different methods of insulating a cavity and maintaining cavity trays & dpc's.
