I did my undergrad at Cambridge and then went onto Brown for my Masters and this strikes me as very correct. Certainly British undergrads are a lot better read and can write a lot more coherently/elegantly. While they do dig deep into their own subject in the UK, it is true to say that most of my students who did English Lit could have a coherent political philosophy discussions or discuss film or art etc. Equally, us political science types had at least some appreciation for the literary canon (although it is funny how differently composed it is across the Atlantic).
