The docs give some good examples of one use of Directive: to avoid nested graphics directives. Thus the example Plot[{Sin[x],Cos[x]},{x,0,10}, PlotStyle->{Directive[Red,Dashed],Directive[Blue,Thick]}] from the "home page" of Directive, although wordier, is to my eye easier to read than the equivalent: Plot[{Sin[x],Cos[x]},{x,0,10}, PlotStyle->{{Red,Dashed},{Blue,Thick}}] The longer and more numerous the directives are for the various elements of a plot or graphic, the more useful Directive becomes in untangling the syntax for the eye.
