Both schools are great, it really depends on what your expectations are, your preferred field of work and where you are from.
Expectations: NYU is in Greenwich Village, i.e. downtown with lots of cool restaurants, bars, jazz clubs, etc. nearby. There is no "campus" feeling at all, but you are in the middle of the most exciting city of the world with all its advantages and disadvantages. Columbia is on a very nice campus on the edge of Harlem, the neighborhood is nice, but it cannot be compared to Greenwich in terms of nightlife (lots of student bars though). However, the subway takes you really fast midtown or downtown (20-40 minutes depending on where you are heading).
Field of work: If you are into taxation, I would definitely take NYU, if you are into corporate, Columbia. NYU has a great IP/competition program with an impressive course offering, but Columbia has some of the brightest minds in IP/competition too (although the choice of classes is really not comparable to NYU in this field).
Where you are from: In some countries (including the USA), an LLM from an Ivy League school (such as Columbia) is in fact more impressive and more valuable on your CV than one from NYU. In other countries, most lawyers really do not care as long as you have been to a top 10 school.
Finally, you may be aware that there is a Columbia/NYU student exchange program that allows you to take one class (each semester) at the other school, although you can only choose among a limited list of classes. So either school you choose, you will be able to get at least a glance of the other...
