Hated both on my previous car. Running Hawk hp+ now, yes they dust alot, yes they squeek horribly when cold, yes they stop HARD!!!! I hear the HPS' don't hold a candle to the HP+ from a friend who has used both.
I'd also recommend Porterfield R4S, very low dust.
I had read about the brakes on the forums for a while but, at the time I was a manager at an Advanced Auto and tried the Bendix Ceramic CT's they carry. They are a bit pricey ($112), but I am beyond impressed with them. My old ones left constant dust and clearly faded when I needed them most. These do neither. They feel like a major upgrade and I do not think I have ever seen dust. And, unlike the hawks I keep reading about, they have NEVER squeaked.
I'm currently running the EBC Redstuff - lots of dust, squeak when cold, but brake hard and have not had them fade yet (this includes some road track use). Came off stock pads to these, and love them - will be replacing them with the same.
Can't comment on a comparison, have only run these and stock.
