It varies per country on what kind of politics and government they have. For some reasons, I'd agree about politics and having no political party is the best. Like everyone is from individual sectors that they're representing and whatever the economy is demanding, they might be the best leader at that time.
Monarchy is what you're describing and based on the long term effect of it, it seems good to those countries that have this type of government. But I'd love to hear it from an actual person living in those countries that have this form leadership. Because by the books, they look great but in actuality, I have no idea.
