How does the LL.M program rank against other U.S. Universities?

I always hear that Georgetown is very good if your field of interest is International Law... And I saw in this website that it is ranked as fourth in the US in International Law (NYU, Columbia, Harvard, Georgetown, Yale is the order). But that is all I know. If anybody has further information, it would be great!

Having a CDN law degree and a LL.M from Georgetown, how does that look in terms of potentially landing a job at a decent NY firm?
