It depends. If it’s boxed chocolates or candy bars with fillings, I like both milk and dark equally. If it’s plain chocolate, I give dark chocolate a slightly higher score over milk. If it’s Easter, I must have a good quality white chocolate lamb.
The only one I am not particularly fond of is the flavored chocolate (whether mint, or citrus or whatever). I prefer the flavor of chocolate with a filling over a chocolate with the flavor mixed into it.
