Probably not since they are different compounds. Since all might be GG
rated, then the actual braking effect itself might match to a degree,
where they will differ is in their ability to handle and dissipate heat
and, equally importantly, manage *disc rotor wear*. Bottom line, your
choice of brakepad type will be determined by your driving style. The
ceramics would be fine for most use and their manner of operation tends
to contribute to longer disc life. On the other hand, if you tow heavy
loads or are a bit of a tearaway and brake hard, low metallic or semi
metallic might work better for you. The downside will be that those pads
will wear the disc much more.
