What is the number 1 Korean kimchi?

I'm curious, could you enlighten me on what the "number 1 Korean kimchi" refers to? Is it a specific brand, variety, or maybe a way of preparing kimchi that is considered the most popular or highly regarded in Korea? Additionally, I'm intrigued to know if there's a distinct flavor profile or ingredients that make this particular kimchi stand out from the rest. Can you elaborate on what sets it apart and why it's considered the number one in Korea?
