They’re both good and similar in rep imo. Warwick has been a recent climber in the ranks and does have some very good other courses eg CS which helps its reputation. Nottingham is ranked slightly lower atm, has dropped a bit but it’s been in or around the top 10 for many years, and law is one of its flagship courses. Consistency imo is better than a Uni shooting into the top ten but then falling off again - which does happen with some.
Both I believe are target unis and I don’t know about Warwick, but I would think like Notts that Warwick will hold plenty of networking events with bigger firms and have several excellent law based societies.
I don’t think there’s enough between them not to pick Warwick & take the bursary. So I’d go with that. I’m sure you’ll have a great time & get a good degree with plenty of opportunities.
