I applied for LLM programs this year and my primary focus is antitrust law.
Since only NYU offers specialized antitrust LLM among T14 law schools, it might be more pertinent to ask which specific courses or teachers are most recommendable among the related courses offered by the schools. I wonder whether the current applicants and graduates would share your thoughts on which courses are on your mind and why they are so good.
There are some candidates below (they are big names, but the more important thing for an LLM student is whether they are good teachers.):

Harvard: Louis Kaplow, Einer R. Elhauge
Chicago: Randy Picker
Columbia: Harvey J. Goldschmid
NYU: Eleanor Fox, Harry First
UCB: Daniel Rubinfeld
UPENN: Christopher Yoo
Georgetown: Robert Pitofsky, Howard Shelanski

You are more than welcome to add more names and details of the courses. Thanks very much.

I would def add to your list Daniel Crane and Damien Geradin, from the University of Michigan. Very well known in their areas of practice, but most importantly also great professors!!
