If you had to be honest, would you say that the average lecturer/teacher/academic who provides education to students at Oxford or Cambridge University is better/more intelligent than their counterparts at a different university, especially the less prestigious the university is?
This is asked because if you look at the background of certain professors at Oxford for certain subjects they tend to have really illustrious academic credentials often having gone to Oxbridge themselves whereas professors teaching the same subject at some other university like Liverpool or Canterbury tend not to have gone to Oxbridge and have gone to less prestigious universities. Also, it seems like it is often the case that the head of a certain department at Cambridge has previously worked at Oxford whereas the head of a particular department at Birmingham may have previously worked not at Oxbridge but at Falmouth.
