Masters in International Relations

I'm an international student looking to come over to the UK to pursue my Masters in International Relations. The three schools I will be applying to will be LSE, KCL and UCL. Technically the program at UCL is in International Public Policy. I've read a myriad of rankings, watched tons of videos. But I wanted the opinions of people who are actually based in the UK.

What are some of the pros and cons of each school?
