another way to think about it this:
What are you trying to improve?
Stopping distance?
Brake Fade?
Noise?
Dust?
For many of us the problem we want to fix is a temporary thing and not constant. As was mentioned above, if your worried about track issues, than have a track set up. Rotors and pads are fairly easy to change and with a little bit of prep can be done quickly for a track weekend.
