i recently had to decide myself which university to go to. i was also interested in applying to oxbridge. i wasn't at all interested in going to LSE because of its situation. For some people the idea of living and studying in london is great...for me it just wasnt the right choice. Often the london uni's offer only 1st year accomodation and then you need to find yourself somewhere to live elsewhere (in london..not exactly cheap as chips) and as its not a campus, you lose a little of the community feel. it just depends what it more appealing to you.
as for oxford and cambridge..well. i was looking to study maths at oxbridge and noticed that cambridge offered a course based more on the pure side of mathematics whilst oxford's had a little more variation and so i opted for oxford, but each to his own.
i would say that whichever of the uni's he decides on, the standard of teaching, subject facilities and the depth of the course will all be very similar and so i would suggest going to open days at each of the uni's to get a real feel for them. thats the only way you can really tell if you're going to enjoy spending the next 3/4 years there.
at least...thats what i think
