Where is it better to study LL.M. International Commercial Law? I have been admitted to universities in the Netherlands, Switzerland, and the UK, but I don't know which University and country are better?

I have been admitted to Leiden, Rotterdam, Groningen, Fribourg, Essex, and Swansea. I am still waiting for being admitted to Sussex and Bristol.

Please state your opinion regarding living costs, employment after graduation, ranking, etc.

Thank you!
