Ive used ceramic, semi-metallic, and non asbestos organic pads before. Ive never had an issue with noise. When I bought the LS, the brakes were squealing. I took a look and they were almost new. I took them off, and sure enough, they were dry all around. I sprayed everything down with brake cleaner, lubed everything up, and put them back in. No issues since.
Remember that when brakes squeal, its usually caused by metal to metal contact, such as the pad sliding on the bracket or the wear sensor touching the rotor. It can also be caused by vibration, which is what creates sound. By wiping down the backing plate with a layer of grease, you minimize the possibility of the pad vibrating on the caliper since the grease will act like a cushion.
