^ the post was generally okay, except that I don't think LSE has a significantly stronger economics program compared to Warwick at the undergrad level. LSE doesn't also have a significantly stronger program compared to Warwick and Durham for undergraduate education on all the rest of the programs. In fact, Warwick and Durham have many areas that are stronger than LSE's. The maths at Warwick, for example, would eat LSE's math alive. Lol... Maybe for grad and postgrad education LSE is stronger, but not at undergraduate level, definitely. Top employers wouldn't choose LSE Econ grad over Warwick Econ grad purely on the basis of school affiliation. The same thing applies for the rest of the programs amongst LSE, Warwick and Durham. And there are fields where Durham excels in. Durham is quite strong in physical sciences. It Physics dept, for example, is world-class or on par with Oxbridge and superior to Imperial's.
Times have really changed. London Unis used to be dominating in league tables especially 20 - 30 years ago. Their reputation was only slightly behind Oxbridge's. But that isn't quite true these days anymore for Warwick, Durham and St Andrews have really caught up in prestige level as well in the areas of student selectivity, teaching standards and employment prospects. Although I would admit that engineering at Imperial is still superior to all Uk unis except Oxbridge's, even at the undergrad level.
To the OP, if you're form London and would want to experience living outside London for 3 years, you will never be disappointed with Warwick. I supposed you wouldn't as well in Durham.
