What is the best Uni in the world?

Could you elaborate on your thoughts about the question, 'What is the best university in the world?' Is there a specific criteria you're considering, such as academic reputation, research opportunities, or student satisfaction? Or perhaps you're looking for a university that excels in a particular field of study? It's a subjective question, so I'm curious to hear your perspective and what factors you consider most important in determining the 'best' university.
