First of all I will say that I have been taught and used both methods and I see little practical difference. I think I tend to use the method described in the FAA Airplane Flying Handbook.
The objective of a good final approach is to descend at
an angle and airspeed that will permit the airplane to
reach the desired touchdown point at an airspeed
which will result in minimum floating just before
touchdown; in essence, a semi-stalled condition. To
accomplish this, it is essential that both the descent
angle and the airspeed be accurately controlled. Since
on a normal approach the power setting is not fixed as
in a power-off approach, the power and pitch attitude
should be adjusted simultaneously as necessary, to
control the airspeed, and the descent angle, or to attain
the desired altitudes along the approach path. By lowering
the nose and reducing power to keep approach
airspeed constant, a descent at a higher rate can be
made to correct for being too high in the approach.
This is one reason for performing approaches with partial
power; if the approach is too high, merely lower
the nose and reduce the power. When the approach is
too low, add power and raise the nose./I]
I think the problem with many of these debates is that we seem to take two legitimate methods and assert that method (A) is the only way to do it, whilst method (B) will result in "blood on the tarmac" if this true would there not be flying schools out there with much higher accident stats?
I would hope that as rational and logical pilots we would not be overstating the dangers of one legitimate method over another, whilst one method may have advantages the fact that both are routinely taught and written about must tell you something.
