My thinking is that pulse up/glide down is better, because the fuel savings is achieved in the P&G technique by the glide phase. So extending or maximizing the glide would be more beneficial.
And sickpuppy has a good point about the aerodynamic penalty of pulsing down.
P&G may be an 'advanced' technique, but it's accessible immediately, unlike waiting for the weekend/spare moment to install the vac gauge to DWL.
