This is something where there's lots of opinions, and I think because every ride is different, its hard to conclude anything with any certainty.That is interesting. However the point I was trying to convey is the Engineering dept at manufacturers spend a lot of time figuring out what will give the most effective braking while also taking into account rotor life, etc.
People have claimed that the EBCs are harder on the rotors. But, like tires, it all depends on what type of riding you've been doing. If you get up to speed on the Interstate and don't stop for 300 miles, and do that day after day while touring, you're going to get a hell of a lot of miles out of a set of pads and your rotors will last forever as well. If you're racing around in the mountains and braking like a GP rider, not so much. Or, doing a lot of stop-and-go riding around town.
So, without any controlled testing, I'm inclined to believe that one company's HH friction is more or less the same as anybody else's, that's why they have a standard in the first place. I can't understand if you brake with any HH friction compound, how one could be easier on the rotors, because the friction is what stops the bike, and that same friction wears the pads and rotors. I could believe that perhaps the HH friction range is fairly large, and Honda pads are on the lower range of the HH spectrum, and EBC on the high range, but I have never seen any data to address that question. If anyone knows anything about that I'd like to hear what they know.
