I've used Dr. Colorchip and if you follow their process, the paint fills the chips pretty well and the repair would be very difficult to see. The touch-up paint that comes in those little pens is much harder to get to fill the chips and bring them level with the rest of the paint, resulting in a more unsightly repair.
