Hello and thanks for asking this question.
All ceramic magnets impart a fast tracking punchy delivery, whereas the alnico version of any given pickup will be warm and slightly more 'vintage' or 'organic sounding. If you want to clean up under gain for delicate chordal work, alnico 4 or 5 will suffice.
I've noticed that ceramic will do it, but sound sterile by comparison.
When wide open, the bridge ceramic magnet will lower upper frequencies and push midrange, making it a good choice for heavy blues, rock and shredding (long hair is optional)!
Paradoxically, the alnico magnet under distortion will spread the frequencies across the sonic spectrum and have a more transparent sound.
A matched pair of any Bareknuckles will do whatever they claim to do perfectly well and in a professional manner, but it may be a good experiment to have alnicos for the neck and a ceramic magnet for the bridge.
Whatever style you choose, enjoy.
Regards
