First ask yourself if what you have is acceptable? Does it stop well? How many miles did you get out of your old pads? Do they fad on a hill?
Brake pads that grab better are not necessary better pads. I'll bet without antilock brakes your old pads would lock the wheels up. Can't get much better than that.
From the factory, my Durango came with semi-metallic pads. Great for heat dissipation and towing. At 120,000 miles I was on my 3rd set of rotors with the original pads. I would call them TOO hard of a pad.
In my humble opinion, Nothing wrong with just changing the pads when they are worn out. Rotors are also a consumable item, but not before the pads.
A good balance is a pad and rotor combo where you need new rotors about every other pad change. But that is also rating pads and rotors on periodicity of changing, not performance.
I guess it goes back to performance. If you old ones were satisfactory in regards to performance and life, I would stay with them.
I'm just trying to point out you can go to an HD pad, but may wear you rotors out quicker.
