Tough to pick as they both are awesome. However, as a south Florida resident I would go with white as that color tends to stay much cooler in the sun. I moved here with a black car and sold it after the first summer. I now have a white car and there is a world of difference in the temperature when you get in and how quickly it cools down.
Something about the white one... more character? Black around the taillights, spoiler, bumper and wheels looks really good.
