Would it be possible to know which 9 institutions you have already chosen (it will give us all a picture of what you are looking for), whether you have decided to take a specialised LLM or not, and the area(s) of law you are interested in, and your future career plans? As you realise different institutions will have different strengths, also each University will have different options at the postgraduate level and the variation can be great.
In addition what are the main factors you are interested in: prestige, location in the Country, type of University City/Campus, size of University/Law Faculty, size of postgraduate body etc.
