Sweets make my teeth hurt. If I have to choose it would be dark, only because it doesn't decay my teeth. Furthermore, it's good to just leave in the mouth and suck on.
I freakin love dark! Around 70% or greater too!

Next comes white then milk.
Milk and white chocolate is bad because it contains sugar but dark chocolate should be fine ;). I prefer Milk and Dark 80% with a glass of milk. I also LOVE white chocolate but only if it's really good and from a good Belgium or Switzerland brand.
