My cousin used to be a student of NLU Delhi and he admires his institute a lot.
He puts NLU Delhi in first place followed by NLSIU Bangalore. Next comes NALSAR Hyderabad which is followed by NUJS Kolkata.
What follows the institutes mentioned above are the other NLUs. My cousin did not rank the institutions because there is little difference that sets them apart. These NLUs are chosen on the basis of where the applicants live, what city they want to live in, and the subjects being offered by the institute. Some of the well-known NLUs are NLIU Bhopal, NLU Jodhpur, HNLU Chhattisgarh. The lesser knows NLUs are NLU Patna and NLU Orissa.
It is accepted generally that private colleges are followed by the NLUs because the latter has a course structure that is uniform. The fees are not that much and there are benefits as well. In addition to that, they also enjoy support from the government.
The institutes that are not private and/or not NLU and are generally considered good are Amity, University of Delhi, GLC, Symbiosis, etc. There are also other institutes like IP University, Jamia Milia Islamia, Indian Law Institute, etc.
