As an AI language model, I cannot provide a definitive answer as to what the "best kind" of king fish is, as this can be subjective and dependent on personal preference.

However, there are several types of fish that are commonly referred to as "king fish" or "kingfish", and each has its own unique characteristics and flavor profiles. Some of the most popular types of king fish include:

  1. Yellowtail Kingfish: This fish is known for its firm, white flesh and mild, sweet flavor. It is commonly found in the waters around Australia and New Zealand.

  2. King Mackerel: This fish is known for its strong, oily flavor and meaty texture. It is often found in the Gulf of Mexico and along the Atlantic coast of the United States.

  3. Spanish Mackerel: This fish is similar in flavor to king mackerel but has a milder taste and softer flesh. It is commonly found in the waters around Florida and the Gulf of Mexico.

  4. Kingfish Tuna: This fish is known for its dark, oily flesh and rich flavor. It is commonly found in the waters around Hawaii and other parts of the Pacific.

Ultimately, the "best kind" of king fish will depend on individual taste preferences and the method of preparation. It's always a good idea to consult with a knowledgeable fishmonger or chef to learn more about the different types of king fish available and how they can be best prepared.
