I think the reason the ceramic pads 'aint biting so hard is because they only work properly at very high temperatures. For example, the ceramic brakes on the Porsche GT3-RS can reach temps of 900 degrees CELSIUS!
Ceramic brakes, IMO, are a bit of a waste unless you frequently track your car. Even conventional racing pads are noisy and less effective unless they have serious heat in them. In normal driving, this can be a liability.
