I compared Magnavox Alnico and FC speakers of the same design, and FC was better. More detail, less distortion.
All permanent magnet speakers suffer from modulation of gap magnetic field by voice coil. If the field coil is driven beyond yoke saturation, there is virtually no gap field modulation, resulting in less distortion.
Another advantage is lower Le at saturation, which allows better HF extension in a full range driver.
