There are a few other recent threads on this same topic. Nottingham was seen as a better choice than Queen Mary however Queen Mary had the London factor which was persuasive.
The geographical location is irrelevant and this has been endlessly discussed on this forum. Forget about the London factor - Nottingham is the correct and best choice for an LLB.
I think it would be remiss of you not to pick Nottingham tbh. dont be scared off by that 2:2 myth, back your ability and have faith in yourself and its a non issue.
