Don, the difference on "usability" could perhaps boil down to this:
In one case you are trying to peak a signal with a fixed pitched inside noise. There is only a single variable -- the pitch does not change, only the SNR changes as you twiddle a knob.
In the second case (moving the VFO knob), you are changing both the pitch and at the same time trying to optimize SNR. Your ear-brain system has to deal with two variables.
It might be easier to peak a signal using the former technique (at least I prefer it). This is true even when you are trying to peak a signal in a spectrum display (i.e., when you try to peak a signal visually instead of aurally).
With that being said... after successfully peaking the signal, a single button press to move both the tone and the filter to the preferred pitch could be be ideal for me. (My Yaesu does not allow that after peaking a signal.) Programmatically moving the result to the preferred pitch is easy to do too, since the center of the filter peak is obviously known to the software.
