Indoors with walls or ceiling to bounce off and a swivel head I find a diffuser a hindrance.

My (limited) experience is the reverse of this. A diffuser sends light in all directions. Outside, most of this gets lost and a reflector is better. A diffuser works inside as the scattered light can then bounce off of walls and ceilings and more of it will reach the subject.
