Is UCL or KCL better for International Relations Master's programmes?

Hi

I have offers from UCL in International Public Policy MSc and Democracy & Comparative Politics MSc...and from KCL in International Relations MA. I am not sure which I should take (I would probably take the IPP at UCL over the Comparative Politics), because though UCL is highly ranked I don't see it talked about much in relation to International Politics/Relations-type degrees. I have heard of King's War Department, but am worried that the school overall is less well-known and well-respected within the UK and abroad. Can anyone offer me advice as to which programmes are most well-regarded?
