If we are talking SEP then.
If high, but at approach speed you need to reduce power AND lower the nose.
If low - bang in the power and raise the nose - this makes the cows become smaller which is a good thing.
If you are low and slow then power is the only thing which can save you.
Flying an ILS? Totally different technique - set power for configuration and desired airspeed, if the configuration changes then the power required also changes but to maintain the glideslope then stick does it.
There is a big big difference between precision approaches and visual approaches so clearly there is a big difference in the skills involved. If the cows look too big then apply power - if you use stick then you might well find yourself in the pooh.
If ROD is too great in a SEP, low momentum machine, then power is always the answer - certainly on final approach. You can always go around and try again. Try recovering with stick and I think your flying might be finished.
Ask an instructor for the best response when low and slow - pitch up or full power?
