McGill or Concordia for Political Science Undergraduate?

I've been accepted to McGill political science program and Concordia School of Community and Public Affairs that I will double major in with political science. Now I was wondering which option would be considered best in terms of degree value, job opportunities and possibilities to pursue a graduate degree later on. I intend to attend Carleton NPSIA school of international relations later on so I was wondering which option would be best suitable for that.
