NOBODY here will have completed medicine at more than one university, let alone more than one in Scotland. Therefore there will be nobody who will be able to give you a decent/valid comparison of the med schools, or tell you which is the best.
All you can do is go to an open day and make a decision. Don't think 'well I want to go to the most reputable med school'. To get into any med school in the UK is a massive achievement, you don't want to be too picky with a course like medicine. Especially when, statistically speaking, you won't get into even the least prestigious university to do medicine.
hope that wasn't too harsh
