legallady We are wrestling with that factor in the mix too. In any case applying for joint honours it is swings and roundabouts as to which uni is best for DDs subjects. DD1 is telling DD2 to go for a university that according to her friends graduating now seems to have the best name with employers (of the ones she has applied to) but that is not the top one in any tables, general or subject 
I am thinking that having actually interviewed on the graduate milk round myself employer lists tend to be so subjective anyway that beyond Oxbridge and London (not dissing Durham Warwick etc just that employers tend to have subjective lists of where they shop but London and Oxbridge are almost always on them) then anywhere in the top 10 or so is going to be as "prestigious". In any case now the old models of recruitment are breaking down, lots more is online, via often quite extensive pre testing and telephone interviewing etc, and that just to get the internships, and quite often the jobs are going to those who have either since uni, or whilst there, built up impressive CVs of work experience, and of course have developed the skills and qualities that make them attractive to an employer. Quite often they are not graduate schemes at all, but unless you are a graduate you are unlikely to be successful in applying. DDs friend who has got the most wow job amongst her peers so far went to Southampton which as an alumnae I am perfectly prepared to admit may not be regarded by many who post here as "elite". All the girls who have been at Oxbridge etc are asking her for advice on CVs etc whereas I know that it is her personal qualities that have landed her the job.
That is beyond law where they I know some city firms really do only select from 6 or so unis, but then which 6 is opaque. In one case a partner told me it was Oxbridge, UCL, Bristol, Durham and Warwick which doesn't chime with any league tables, general or law. 
What we are now realising is more important for my DD is the emphasis of the courses, so now the modules offered and whether they are in the areas my DD is most interested looks like what will swing the decision. If she isn't studying what she expressed all that "quirky passion" for in her PS then she is unlikely to do as well on the courses and these days if you don't get a 2.1 as far as graduate employers are concerned it seems it is hardly worth bothering.
