Render Quality, Is "Best" really best?

It manifests itself even more obviously in the reflections of the chassis on the surface. In the GOOD rendering, all of the bolts are black. In the BEST rendering, all are silver.

Thanks for this information. I have been working on some renders lately and was wondering exactly the question of if BEST quality was worth the wait.
