Bloody hell, not this old chestnut again...
For aircraft with high inertia, Point and Power works best.
For aircraft with low inertia, Pitch works better.
However in reality, you never actually do one without the other on a "normal" approach and so I struggle to understand why it becomes such a hotly debated issue. Fly the damn aeroplane in the best manner that suits it, don't over complicate it and force it to respond to something that doesn't suit it.
When flying a powered approach, then the throttle needs to be adjusted everytime the pitch is, if you want to fly a steady approach.
If you are flying an unpowered approach, then what's so difficult about having to use just the pitch attitude to control everything?
