That's alright I don't mind telling you on here.
I got a 2:1 from King's. My exam grades were mixed, a couple of firsts, mostly mid to high 2:1s and two 2:2s (oops). My references from my KCL tutors were very, very good though (I got on well with them and worked hard in class), and I have a feeling they said something along the lines of "would have got a first overall if he had been as good in the exams as he was during the year". I got the medical law prize in my third year for my first in the exam+dissertation.
Things got better at the LSE, I really found my niche, and ended up graduating with the highest first in my MSc year, with an offer to publish my dissertation in an academic journal if I put some work into refining it (haven't got round to doing it yet though).
My plan is to have a go at academia, working in legal and political philosophy, particularly Rawlsian liberalism and theories of global justice, perhaps with a view to returning to the UK sometime soon after and combining this with a part-time public law practice at the Bar.
Going to the US for a PhD is very attractive since there is much more funding on offer there than here at home. If you get into a good college, it is likely that you will be fully funded (tuition fees waived plus grant to live on) for the duration of the doctorate. Plus the US PhD is structured differently from its UK counterpart; thesis research takes 3 years (as here) but before you get to that stage you must complete 2 years of attending classes, writing essays and sitting exams (hence 5 year total), effectively doing another MA. I'm keen on this since it will make up for the fact that my undergrad, whilst sometimes relevant for what I'm doing now, was not in philosophy or politics. So I've yet to study most of the major canon yet, and will do so in those first 2 years. I don't regret getting an LLB though - on balance, it was a really good degree.
EDIT: I originally posted about the JD/LLB since I'm just curious about the American law degree. I understand that if I go to Georgetown it might be possible for me to earn a JD from their law school whilst studying for the PhD in their gov't dept., on some kind of accelerated program. If, for some reason, I chose to remain in the US on a permanent basis, I might need to do this if I still want to combine an academic/legal career, since I have a feeling that my LLB alone is insufficient for me to sit US Bar exams.
