It seems King's is thought higher of internationally than nationally, which would be good for you. It is due to it being part of the UoL. We are fourth for law though, in the Times and Guardian rankings, and I think that the law department here is great - we have fantastic lecturers. Maybe you should base your decision on whether you would rather live in a lively, bustling city or a campus university in the middle of nowhere. They are two very different things, both with their advantages and disadvantages, but people usually have a distinct preference. Because, to be honest, if you went to King's or Warwick, your job prospects would be very good. Personally, I love being in London - it's always busy, the nightlife is fantastic, the transport system is fantastic, you can do just about anything here, but many people hate how busy it is.
