How do people on this site rate the LLM in IPR providded by the NUS to U.K. Universities. are there any advantages or is the teaching better at NUS?

I think the comparison is unwarranted because the two cater to entirely different jurisdictions. NUS is taken from a perspective of gaining insight into the working of the Asian markets and the favourite subjects of pursuit over there usually are commercially oriented, along with international law and law and economics of Asia.

UK universities have a more global reach, however, a valid comparison would be limited to that betwenn UOL colleges and NUS. Oxbridge are far ahead and the rest quite behind in terms of global reputation.

Ultimately if you wish to work in the markets of Singapore, Hong Kong, Australia, NUS might good look on your CV. If you plan to move further during your job, ultimately, NUS is well recognised in US as well, especially if you take NYU@NUS, though IPRs are not allowed as a subject in that degree.

For Europe, Common law jurisdictions, especially India and constituents of UK, an LLM from UK would be better.

However, one may bear in mind that neither NUS nor any UK university (except may be QUML) are that world renowned when it comes to IPRs. The best options may be US universities or European universities. You may like to browse through this list:
