Im pretty sure, both Cambridge and LSE will you to the same places in life. Both have advantages that I believe offset one another. LSE has amazing economic research, the top economic professors and is of course a place entirely dedicated to economics. Furthermore, being situation in London has perks socially and career-wise. Cambridge's reputation indeed has that edge, that kick over LSE since it is multi-faculty and has been at the epitome of further education for hundreds of years. LSE in comparison is a relatively new institution. Moreover, the bridge has the advantage of the brilliant 1to1 tutorials where as the LSE professors are renowned for, excuse my French, not giving a ****! But overall its down to you. LSE gears u up for the city, which Cambridge can provide you with also. But Cambridge has that additional academic feel to it. Despite saying this, I am going to chose LSE if i get in (still waiting, conditional from Cam atm) purely because I prefer London life to the dull Cambridge village and also I don't fancy writing 2 essays a week! But that's just me, I'm a little lazy and quite motivated by clubs
