Hi Flateric,
First of all, how was your GMAT? I hope it went well.
I have a doubt, are you looking for an MSc in "Economy Management" or you meant "Economy or Management"? I will assume you were asking about the latter. To begin with, it is normal that universities offered both MSc and MBAs, because they are different programs. However, it is true that in the case of MSc Management, the program is similar to that of the MBA, so if you are interested in pursuing an MBA in the future, maybe you shouldn't do a MSc in Management next year.
If you are looking for the best universities, I think the best you can do is to play around with the FT rankings, which you can find here
https://rankings.ft.com/businessschoolrankings/rankings. Notice that there's a ranking of MSc in Management programs, in which universities' ranking can differ from that of the Top European Bschools ranking. Notice too that, given the short life of the MSc program in Management, some top universities such as London Business School are not present in the rankings yet. Apart from the default ranking, you can play with the variables that interest you the most, in order to see the best options. For instance, a lot of French Bschools are in the top10, but if you were looking for a multicultural class, you will observe that ESADE or Cass would be a better choice.
About the supposed MSc in Economy, I believe it is called MSc in Finance, and you can find a thorough list in the link I provided to you before.
I hope it's not too late,
See you.
