Doesn't sound like a good idea to get too religious about one approach or the other.
After a couple of years' flying gliders, it was pretty clear to me that you control speed by attitude, and that by elevator. Then I decided to renew my IR. It took me a couple of goes to work out why I couldn't fly ILSs very accurately, until it was pointed out that the technique there was to fly rate of climb by attitude, and speed with the throttle. (If you're off the glideslope you're going to fix it much faster in the short term with the elevator than power).
Bottom line - we use both. Which you use as the primary depends a bit on what you're doing.
