Transferred over to Manchester for 1 year from SIM. Prestige wise its about the same. Alot of law grads here cannot find find a training contract because most law firms here take in anyone from any discipline as long as you meet their minimum requirement.
Most law grads from their not so top Uni either go back to their own country and practice law or end up working in Tax or something completely unrelated. In the UK, all these job fairs, law fairs are only present to provide prospective candidates information and nth else.
Choose somewhere you will enjoy living for your next 3 years. Prestige wise, both are not oxbridge so they are about the same
Just my 2 cents
