In order to answer at the best to this question, it would be useful to know what your background so far is. As I understand, you are on the process of deciding which University to attend. But are you talking about Bachelor, Master, MBA, ...?
As a very general reference, if you are looking for a business education, you can just check which are the top Universities according FT Rankings:
Business Schools in Europe: http://rankings.ft.com/businessschoolrankings/european-business-school-rankings-2016
Master in Management: http://rankings.ft.com/businessschoolrankings/masters-in-management-2016
Talking instead about non-business education, any quantitative background, such as engineering or physics, is usually highly appreciated. To this regards, I would say that, at an international level, it matters a bit less which University you´re coming from and each country has its own most wellknown Universities.
Last but not least, MBB Firms look for diversity. Therefore it´s not uncommon to find in a McKinsey office a consultant whose background is, for example, Litterateur, Philosophy or even Medicine!
