League tables, rankings, prestige, reputation etc are all fairly meaningless and they are not good ways to choose a Uni. mainly because they all nebulous nonsense invented by newspapers and marketing companies. A great deal of utter nonsense is spouted about all this stuff on TSR.
The only people who get obsessed with this are school leavers. Mainstream employers don't actually care whether you went to Durham, York or Cardiff. Its a degree. And its from a Uni they have heard of. That is all those employers care about.
In terms of Law there is an equal amount of silly 'I've heard', 'My dad says' type statements here about the nit-picking difference between Unis. Yes, of course there is a difference between Bristol and London Met - but mainly in the A level grades they require. Both courses are recognised by the Law Society therefore clearly both turn out totally acceptable Law graduates.
It would appear that certain London law firms have more employees from one Uni than others, but the reasons for this are NOT because that firm actively seeks candidates from that Uni. It is because there has to be a majority from one Uni (think about that fact), and the chances are that that becomes what is known as a self-fulfilling prophecy - grads from Uni X will apply to Firm Y because they think they have more chance of getting a place there because of the existing employe profile. Grads from a Uni that has no alumni working at that firm will conversely probably not apply thereby reducing the chance of that profile changing. Grads from all RG Unis tend to be more confident and have a higher sense of entitlement than those from 'other' Unis - they are more likely to apply to 'top' employers in ANY field because of this expectation of success.
The idea that if you do your Law degree at Nottingham (or wherever) your life chances are immediately better than doing your degree at Newcastle (or wherever) is frankly utter bunkum.
Life is what you make it. You do not come out of ANY Uni with a barcode stamped on your forehead that allows you an automatic wonder job and guarantees any of you a ridiculously happy life.
So .... stop winding each other up with all this 'my Uni is better than yours' or 'which is better, Uni X or Uni Y' type nonsense. You need to look at the details that will mean you are happier at Uni A over Uni B - course details like interesting optional units, extras like study abroad or work placements, in-house work experience like law clinics, which Uni you'll enjoy being at, which city you can afford to live and which city you think you'll enjoy living in. No League Table can tell you any of this. That is why you went to Open Days all those months ago - so you could get a feel for the difference in each Uni environment and atmosphere. Go back to that. Think carefully about where you will feel comfortable and happy. Make your choice.
