Which NIT/IIT is best for pursuing ECE and for Computer Science?

There are many good departments in the country that offer great education in CSE and EE (in many NITs they have a separate branch called ECE). Let me explain about IITM. The Indian Institute of Technology Madras is one of the foremost 'Institutes of National Importance' in higher technological education as well as basic and applied research. It is ranked number one in India according to NIRF, and also amongst Research and Teaching Institutions in Engineering by the MHRD. IITM is also among the top 50 universities in Asia. It offers world-class programmes in both the Electrical Engineering (EE) and Computer Science (CS) departments. Alumni from these departments have not only worked at the biggest tech giants worldwide but have also gotten admissions to top universities like MIT, Stanford, Berkeley, etc. Some of the alumni have also founded big companies like Rubrik. The faculties in these departments themselves hold degrees from top universities around the world. Both these departments also have top-notch research facilities, with some exciting ongoing work. Please go through the department webpages (EE, CSE) of the same for more details.
