• IIIT Surat has a dedicated and experienced faculty that is solely focused on computer science and information technology. This ensures that the quality of education is of the highest standard.
• While Thapar University may have a higher overall ranking, the faculty quality in Thapar may vary from bad to good, and you cannot be sure which one you will get. In IIIT Surat, the faculty is specialized in computer science and information technology and is of high quality.
• IIIT Surat has a specific focus on research and innovation, which means that students have the opportunity to work on cutting-edge projects and contribute to the development of the industry.
• IIIT Surat provides excellent placement opportunities in reputed companies, both nationally and internationally.

However, it is essential to note that institutions like Thapar University and NITs provide an overall development of students through extracurricular activities and other programs, which IIIT Surat may not. So, it is crucial to consider all factors and choose an institution that best suits your needs and aspirations.
