What brand of dark chocolate is the best?

I'm curious, have you ever sampled various brands of dark chocolate to find the ultimate one? If so, could you please share your thoughts on which one stands out as the best? Perhaps you've discovered a unique flavor profile, rich cocoa content, or a satisfying texture that sets it apart. Additionally, do you think there's a particular region or country that produces the finest dark chocolate? I'm eager to learn more about your preferences and the criteria you use to judge the quality of dark chocolate.
