I don’t think anyone choosing IIT Delhi over any other engineering college has made a wrong decision given the opportunities and life experiences that come with it. While both are crucial, your choice of Institute is more important than your branch. 

Here is a friend's journey for your reference l was a BTech student (Civil) at IIT BHU with a rank of 3600. 

• First, he completed a Nanodegree program from Udacity in Self Driving Cars and Machine learning
• Next, he worked as a Derivative Trader in Future First where he performed Machine Learning and Deep Learning algorithms.
• After gaining great experience and exposure he joined Quantela Inc for 2 Years where he worked as a Data Scientist.
• Today, after a lot of job switches and immense experience he is working at Derq in Dubai as a Machine Learning Scientist and doing Online MS from Georgia Tech University in Computer Science.

This journey of a 7-pointer Civil Branch student to a high-tech CS company proves that branch does not matter in the end. He made the most of his campus life and kept struggling to switch his branch and eventually succeeded. That being said, you have made the right decision as only IIT Delhi can give you the right set of opportunities and exposure and not DTU.

 IIEST Shibpur CSE department is one of the oldest and most established departments in the country. 

• Placement: CSE department at IIEST Shibpur has a good placement record, with many top companies visiting the campus every year. In 2021, the average salary package for CSE students was around INR 10 LPA, with the highest package going up to INR 35 LPA.

• Faculty: IIEST Shibpur has highly qualified and experienced faculty in the CSE department, many of whom have earned doctoral degrees from top universities in India and abroad. They are involved in cutting-edge research and often collaborate with industry and other academic institutions.

• Infrastructure: IIEST Shibpur has a state-of-the-art infrastructure with modern classrooms, well-equipped laboratories, and a well-stocked library. It also has several research centers and labs for students and faculty to engage in cutting-edge research.

IIEST Shibpur is one of the top engineering institutes in West Bengal, along with IIT Kharagpur, NIT Durgapur, and Jadavpur University. Its placement record is on par with the top NITs, making it a popular choice among engineering students.

BITS Hyderabad is definitely better than VIT Vellore for CS. Here are some reasons for the same-

• Coding Culture- Even VIT Vellore has a decent coding culture. But when it comes to any of the BITS campuses, the coding culture over there is far more superior. The environment at BITS is such that one feels extremely motivated to learn and build new stuff. The BITS faculties are highly qualified and supportive.

• Crowd- Getting into BITS is difficult, and there are no NRI or Management quota seats. Each one of the students gets in through pure merit. Because of these reasons the BITS Hyderabad crowd is overall better than the VIT Vellore crowd.

• Placements- The Computer Science department of BITS Hyderabad witnesses better placements than VIT Vellore. But even VIT Vellore is good for CS placements.

• Course Intake- VIT Vellore intakes a lot more students on a yearly basis. Though the competition is much higher at BITS Hyderabad, the end results are more fulfilling for each one of its students. 

Thus, I would recommend you choose BITS Hyderabad for your B.E. in CS. 

My cousin graduated from DTU in CS. According to him, these institutions can be ranked for CS in the following order-

1. DTU
2. NIT Calicut
3. IIIT Allahabad
4. NSIT (now NSUT)
5. IIIT Delhi
6. DAIICT

DTU is considered one of the best Indian institutions for CS. Therefore, you should go for DTU if you get the opportunity. Every technical society at DTU, be it IEEE, ASME, CSI, IET, or even the small ones, gives great value to coding competitions. Thus, coding classes and competitions are held on a regular basis.

For those who want to work on real-use-productive coding instead of passive-competitive coding, there are many opportunities at DTU. DTU has several societies, and there are student entrepreneurs who are always in dire need of talented coders. 

DTU also has a locational advantage. Being situated in the capital of India, it offers students great opportunities and exposure, not just industrial but of all types. Gurgaon is the IT hub and since you will spend 4 years of student life in Delhi, if you land a job in Gurgaon after graduating, you will have been accustomed to the region by that time.

The seniors at DTU are helpful and there is a strict anti-ragging policy on campus. The faculty consists of learned and helpful professors. The non-tech placements are also quite good at DTU.

DTU has huge brand value, long-standing history, and it is the mother of a lot of great colleges.

NIT Calicut is a good choice as well because it has a good placement record and an impressive infrastructure. In terms of location, however, DTU, NSUT, and IIIT Delhi are at an advantage.

You can consider all the above factors and finally decide which of these institutions is the right choice for you to pursue your CS.

If you are looking for the best college for CS then go for DTU among the aforementioned institutes. Although all the colleges will offer great opportunities, DTU has an upper hand in certain areas.

• DTU has an amazing coding culture. Students of every branch be it CS or EP are involved in coding at some level.
• Technical societies like IEEE, ASME, CSI, and IET organize a number of coding competitions to ensure the active participation of the students. 
• DTU has a number of entrepreneurs who are on the lookout for coders. So here, you will not only learn coding but also implement it.
• Its location plays a big role in improving its brand value and opportunities. 
• DTU has a rich legacy and has given birth to a number of well-reputed colleges. It has a strong alumni network owing to its early establishment.
• Located in Delhi NCR, students are exposed to better placement opportunities in IT companies.
• DTU has an amazing placement scenario. DTU's highest package stood at INR 1.8 CPA whereas the average package stood at INR 15.16 LPA.
• DTU has the highest non-tech placement percentage (47%) among other colleges.

Ultimately a college can only give you the initial kick in your career but the rest depends on your hard work and determination!

While choosing a college for Computer Science, it's important to consider various factors such as the study environment, placements, and reputation of the institution. In the case of choosing between IT at IIIT Allahabad and CSE at the MNNIT, Allahabad, you should consider IIIT Allahabad.

• Study Environment: IIIT Allahabad has a strong background in terms of study environment, with top-performing students in coding competitions such as CodeChef, HackerEarth, and HackerRank. Students at IIIT Allahabad start working on their projects in the second year of their studies, which provides them with hands-on experience in their field of study.

• Placements: IIIT Allahabad has better placement opportunities compared to MNNIT. Top companies such as Google visit IIIT A for recruitment, while they may not visit MNNIT.

However, this does not mean that MNNIT is not a good college, but IIIT A is considered top-class for its placements.

Overall, IIIT A offers a strong study environment and better placement opportunities, making it a great option for students looking to pursue their studies in technology and related fields.

In my opinion, B.Tech CS from IIT Gandhinagar is a better choice. I am listing down the reasons why I would’ve chosen IIT Gandhinagar CS over NIT Trichy CS-

1. IIT Gandhinagar is one of the best new IITs after IIT Hyderabad, IIT BHU, and IIT Indore.
2. It also has very good placements like NIT Trichy with an average package for CS crossing 29 LPA at present.
3. The government funding is far more for IITs.
4. IIT Gandhinagar has changed immensely in the last few years. It is growing rapidly.
5. Gandhinagar is more developed than Trichy.
6. IIT Gandhinagar carries the highly recognized ‘IIT’  tag.

IIT Gandhinagar is the 11th most preferred IIT. It is expected to show more growth than NIT Trichy in the coming years because of its IIT tag and greater government funding.

Thus, I would suggest you go to IIT Gandhinagar for your CS.
