The choice of college and branch totally depends on your inclination and career prospects. Yet, a few pointers you might consider 

For MBA/ non-core jobs/Startups: IIT Delhi Textile is the best choice if you are looking for any 3 of these options. Its excellent location provides enough exposure to give you access to unimaginable opportunities. Many events hosted by industry experts, CEOs of big companies, and successful entrepreneurs will give a better insight into the startup culture. Moreover, students preparing for competing exams can easily access coaching centers nearby.

Research in Biotechnology: If you are interested in research in general or Biotechnology specifically, then the Biotechnology at KGP is an excellent choice. It is one of the most demanding fields in terms of research and general growth. With a good CGPA, you can find a research internship or you can apply for MS or Ph.D. Even job opportunities are plentiful. 

Campus: IIT Delhi is better because of its small size and location

Lastly, Engineering Physics from IIT Guwahati should be considered only if you are genuinely passionate about Physics and want to pursue a research career in the same. The curriculum comprises high-tech mathematical concepts and is a good option to pursue a career in economics and computer science.

Both IIT Guwahati and IIT BHU are highly comparable to each other in terms of academic and professional excellence. However, both have their own unique strengths and weaknesses and my answer will guide you to make the most appropriate choice 

Course structure: The course structure of both EE at IIT BHU and ECE at IIT Guwahati is similar and has very few differences. 

Infrastructure: IIT Guwahati has better infrastructure because of its later establishment. IIT Guwahati is known for its extremely beautiful campus with rich natural beauty.

Alumni: Being older, IIT BHU has a longstanding legacy of excellence. This has a positive effect on the placements.

Culture: IIT BHU has a rich and dynamic work culture that is generally not found in engineering colleges.

Faculty and peer pool: Both IIT BHU and IIT Guwahati have excellent faculty and peer pool being reputed institutions.

Ultimately, it’s all about personal inclinations and there is no fixed right or better choice.

For most students, the end goal of getting admission to a college is to secure a job in a good company. So most of the time placements become the basis for evaluating the worth and credibility of an institute. Here are some points pertaining to the placements in IIT BHU and IIT Guwahati

• Very few core jobs are offered with only 20–25% of people from a branch securing a job in their core companies. This is because very few core companies visit and the package offered by them is less than non-core companies. Thus students flock to non-core companies. IITG is much better than IIT BHU in core placements as at IIT BHU, some faculties and labs are not up to the mark.
• There are multiple non-core companies that offer jobs to the IITians in various profiles such as software development, business analysis, operations executive, and Finance management. IT-BHU offers the best non-core opportunities as the workload is less and placements are great. 
• You can easily change your branch at IIT BHU with very less effort. All you need to do is maintain a good SPI and then change your branch after the first semester.
• Located in the prime area, IIT BHU will give you a feel of Varanasi, BHU Vishwanath temple.

However, for students whose priority is not to get a job but to pursue higher studies and pursue a career in research, IIT Guwahati is the best option. A few aspects and the preferred colleges are

• Placements - IIT-BHU>IITG
• Academics- IIT-BHU<IITG
• Faculties- IITG>IIT-BHU
• Branch change- IIT-BHU>IITG
• Campus infrastructure- IIT-BHU<IITG
• Campus life, culture- IIT-BHU>>IITG

The choice of the institute is a matter of preferences and your career prospects so make sure you set your priorities right.
