Indraprastha Institute of Information Technology - [IIITD], New Delhi

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.

For a better understanding, I will compare both IIIT Delhi and NSIT Delhi based on some common aspects

• Placement : The placement scenario of both the institutes is similar with IIIT Delhi having a slight advantage. NIST's median package stood at INR 16 LPA while IIIT Delhi's average package stood at INR 23.72 LPA
• Campus : NSIT has a higher campus than IIIT Delhi but is old. IIIT Delhi is a relatively new institute so its infrastructure and campus facilities are modern.
• Hostels : NSIT has bigger rooms than IIIT Delhi but IIIT DELHI has rooms with better facilities. There is the provision of AC at night in summer and a heater at night in winter.
• Faculty : IIIT DELHI is the clear winner as its faculty pool is even better than some IITs.
• Reputation : Being older NSIT enjoys a better brand value and recognition both in and outside India. 
• Coding Culture : IIIT DELHI has a much better coding culture than NSUT because the institute is CS centered.
• Fees : IIIT Delhi charges higher fees around ?4.62 Lakhs (1st Year Fees) while NSIT fees are around ?2.29 Lakhs (1st Year Fees)
• Clubs : NSUT has a better campus life and extracurricular culture because of the various clubs so it has an edge in this aspect. 
• Campus Life: IIIT Delhi has a very rigorous and tiresome campus life while NSIT has a more laid-back campus life. 
• Curriculum : IIIT DELHI has a more updated and modern curriculum in comparison to NSITs outdated curriculum irreverent to the industrial trends.

Overall, if you want a rigorous campus life more focused on academics choose IIIT Delhi but if you are looking for a relaxed experience NSIT is the one for you.

All the aforementioned institutes, DTU, BITS, NSIT, and IIIT Delhi are excellent colleges that are well-recognized in the tech sector. As a whole the curriculum and placement opportunities for CS offered by these colleges are quite similar. The average package varies slightly but the individual differences compensate for that. Here is a comparative analysis of the placement statistics of these colleges 

However, if you look from the angle of research , IIIT Delhi certainly is way ahead than the other colleges. Its research-oriented institute is primarily established to conduct cutting-edge research in the field of CS. While BITS Pilani also has a decent research culture, DTU, and NSUT are nowhere near IIIT Delhi in terms of research. IIIT Delhi students have a lot of projects to work on under highly learned and passionate faculties. The exposure these students receive is unmatched and they are offered excellent opportunities in terms of both in industry and for higher education.

So if you want both excellent placements and research opportunities go for IIIT Delhi but if you want a good campus life too that is less focused on research go for BITS Pilani.

All the colleges you mentioned; NSIT, DTU, and IIIT Delhi are run by the NCT government and have similar opportunities and brand value. The choice of the institute here depends more on personal factors than the institute itself.

NSIT: 

• NSIT is located in Dwarka. 
• It functions under DU and offers a 4-year course for a bachelor of engineering. 
• NSIT is an excellent choice for those who want to get IT-related branches like CSE, IT, and ECE. 
• Most departments are at par with DTU departments 

DTU: 

• DTU is a highly regarded technical institute offering superior quality BTech courses
• This institute is well-known for core branches like CIVIL, Mechanical, and Electrical Engineering. 
• The most reputed branch of DTU is Mechanical Engineering, often compared to IIT Delhi Mechanical Engineering.

IIIT Delhi: 

• IIIT Delhi is the perfect destination for programming lovers
• The CSE curriculum of IIIT Delhi is way better than that of DTU and NSIT.

So, it precisely depends on the kind of branch you want to get if it’s all about programming go for IIIT Delhi, if it’s CSE, IT, or ECE go for NSIT but if it’s core branches like Mechanical, Electrical, or civil engineering DTU is the best option.

IIIT Allahabad is better than IIIT Delhi. It offers great academics in IT and has an extremely competitive campus environment. Students of the institute dominate almost every major coding platform. Over the years IIIT Allahabad students made their presence felt in competitive coding events such as GSoC, ACM ICPC, and Google Code Jam. 

IIIT Allahabad placements 2022 witnessed an average CTC of INR 19 LPA. The highest CTC offered this year was INR 32.2 LPA. 

On the basis of placements, I would rank the aforementioned institutes in the following order

Bits Pilani, Pilani Campus>|IT H>Bits Goa>Bits Hyderabad>Top 3 Nits>|IT Delhi/NSUT>DTU

BITS Pilani has a better placement scenario than IIIT Hyderabad although its average package is less than IIIT Hyderabad, this is because BITS has a number of branches and the average package is calculated after considering the packages of all branches whereas IIIT Hyderabad has only two branches ie CS and ECE. Both these branches are top branches so automatically its average package becomes higher than BITS Pilani. If you compare the placements of the CS branch alone, BITS Pilani will have the upper hand. However, if you want to pursue a career in research in CS, ten choosing IIIT Hyderabad will offer better opportunities. Basically, IIIT Hyderabad will make you a better coder whereas BITS Pilani will make you a better engineer.

It's important to note that the above ranking is based on placements alone and if you consider the research culture, then NITs will fare better than BITS mainly because they are government institutes and receive huge funds solely for the purpose of research.
