I just got accepted (unconditional offers) by both Sydney Uni VS Kings College London. Its really hard to compare two universities in different countries but I am wondering if anyone knew which school was better..

Anyone can give me suggestions! Thanks

I think it would all boil down to personal preferences.
1) If you wish to settle down in Australia and practice there, Sydney would be good, u might take the concerned subjects that may fulfill the requisite credits which are mandatory for taking the bar exam in Australia.
2) Conversly, the same might not hold good in case you want to enroll as barrister or solicitor in UK.
3) If you wish to enter the world of academics, both might be good. KCL might be good from a perspective of your home country (if you are from common law background) and from UK and European perspective. Sydney would be better from the Australian and American perspectives (though KCL also opens the doors to those regions).
4) As far as subjects are concerned, if your interest lies in comparative law, KCL is by far the better option, just because you get a chance to compare at least 3 jurisdictions (your home country, UK, Europe). The quality of teachers at both institutions cant be compared. Many of the academics at KCL are qualified barristers and some sit as part time judges. Others are authors of uncomparable repute. Still others are flagbearers in their respective fields and one cant go wrong with that fact.
5) If by chance, you had any interest in tax law, KCL houses the Charter Institute of Taxation, and the brochure states that a right combination of courses coupled with some work later qualifies one for accredition with CIT qualifying one to work as Tax consultant in England.
6) The atmosphere in London is uncomparable. All libraries across colleges under UOLondon are inter-linked giving you an incredible and unmatched resource field to subscribe to.

Ultimately, its your goals, aims, interests, strengths and weaknesses that should define which university you opt to join.

I am in general agreement with the considerations raised by jagsmehn.

Personally, I would go to Kings if affordability isn't an issue. The value of an LLM from Australia isn't as high as a UK one. Most Australian universities do not even have a quota for admission into their LLM program.

Thanks and good luck!
