Warwick MORSE or UCL Mathematics with Economics

I don't really think UCL compares to Warwick for maths in general academic terms.
Graduate prospects are going to be similar. Warwick MORSE is pretty well known in the finance sector particularly, but in principle they're both target unis for investment banks/management consulting firms, and otherwise they're pretty much equal anyway.
London isn't really all that special, and it's crazy expensive. I'm not really sure how much you can do in London as a poor student realistically! Getting drunk is the same everywhere and anything else in London you can just do on a weekend visit or spending a few days during a reading week or during a holiday.
