I opted for the sapphire black (metallic) after looking at the two side by side, in a showroom (both are stunning) and under the Florida sun outdoors, where I liked the metallic a bit better. The sapphire is a bit more lively and some say it better hides dust. Frankly, having had 3 jet black cars, I was ready to get away from the funereal hue of pure black but reluctant to leave the stately appearance of black/dark.
