It really depends how you drive.

I notice they grip better right off when wet, don't fade over lots of downhill driving, and don't make nearly as much dust as the OEM pads.

instarx what you posted is not quite true. Brakes must dissapate the kinetic energy stored in the drivetrain before the wheels lock (not that that is desireable) or at least approach the limit of traction. Larger/more efficient braking systems mean that this condition is met sooner.

Couple other tips

Make sure car is supported on jack stands.

15mm socket or box wrench needed to remove the 2 rear caliper bolts . They are on tight. I use a breaker bar to loosen then and then my socket wrench

I use a strap or rope to support the caliper, once removed you will need to hold it up to keep the weight off the the rubber brake hose. I usually tie it up the the spring strut.
You can also just put a bucket upside down next to the caliper and rest it on it. Just keep the weight off the hose

Caliper grease for the sliding pins.

If you had you brake reservoir up to the full level before the job you will need to remove some brake fluid because when you squeeze in the caliper it will raise the brake fluid level . Brake fluid will take the paint off the car.

Also sometimes I use a flat file just to clean up the rust where the brake pads push in

Remove the cap from the brake fluid reservoir before trying to push the caliper pistons back in. I find that my little floor jack works quite well for pushing the caliper piston back in to fit the new pads; there are other things you can use as well, like a large C-clamp.

If your fluid is old and disgusting-colored, enlist a helper to help you bleed the braking system (or, for $50, you can buy a Mitivac system to make quick work of it by yourself). You must be very clear with said helper to NOT under any circumstances let the brake pedal touch the floor of the car - I usually wedge something behind it so they can't.
