The usual differentiation between the two different 'techniques' is that one works best for light inertia a/c (little ones) and the other works better for high inertia a/c.
Next, however, comes the debate about what constitutes a high or low inertia machine.
As said before, do what you need to to keep the a/c going where you want it and don't get too low and slow, you start entering a whole world of problems then!
