Answer

Hola Andrew
You can say both:
¿Cuál universidad es la mejor? or ¿Qué universidad es la mejor?
But using cuál would generally mean that the people involved in the conversation have been talking about some specific universities, so the question with cuál would be referring to which one out of those that were mentioned. However, using qué, although it could also be used in the scenario described before, it is more common on more open questions without thinking of a preconceived selection, as if we were saying, out of all the universities in this region, in this county, or in the world, (a wider scope) which one is the best?
