I was always taught stick for speed, power for rate of descent during VFR training. That motto works well with the constant aiming point method.
In IFR it's all change - now I'm told stick for ROD, power for speed. I'm finding that a high speed ILS in a twin requires very subtle applications of the new formula!
Of course the real trick in VFR is to set the power on base prior to descent and then not touch the throttle until at/very near the threshold - in my experience only works with a light wind and an empty circuit, or maybe thats just me!
