What do you think is the hardest cuisine/most complicated cuisine to cook?

When it comes to flavoring, I always think Thai and Vietnamese is the hardest. It's just that their herbs, spices and vegetables are so rare and they spoil so quick (Lemon Grass, Cilantro/Coriander, Kafir Lime Leaves) and that's why they always have their own mini spice gardens to make the best ones. Indian comes close. But the thing with their spices is it doesn't have to be fresh. I imported some of it and I don't have to worry about it spoiling quick. But skill wise, French chefs just really love to complicate things with really simple ingredients. Complicated bread shapes, Pâtisserie, Garde Manger and even Placage which what makes them expensive despite how unsatisfying they are lol.
