Would you pick LSE over Cambridge?

I was speaking to some Year 13 students today on an offer holder day. They both said to me they hold Cambridge offers but are waiting on LSE - if they get an offer from LSE they'll firm that. This somewhat blew my mind. Am I just being too old and un-cool to think Cambridge is the obvious go to choice?

For reference, I don't have a stake in either, I just think Cambridge is the better choice.
