to spend more or not to spend more? brakes

When I put new pads on my Dakota I used the Wagner thermo-quiet or something like that. A lot less brake dust!
I can't tell if it stops any better. I haven't been in a situation where I needed that feature, and since I never was with the factory pads I still wouldn't know.

In any event, because of the low dusting, I put them on my Duster also.
