CS and EC are very different branches. You need to decide which branch interests you more.

EC is about electronics and how the different electrical components communicate with one another. It involves a lot of Physics. It only involves a little programming. CS, on the other hand, is all about programming. It mainly uses logic and math. 

If you are interested in programming, CSAI from IIIT Lucknow is the better choice. AI/ML is in huge demand in the industry as most things will be automated in the future. Placements and coding culture are top-notch at all these colleges. Students from IIIT Lucknow and IIIT Bangalore perform well in competitions like ACM ICPC. 

All these colleges are good. You should make your choice based on your field of interest.

Your rank is pretty good and you are likely to get both, IIIT Hyderabad CSE and BITS Pilani. However, had I been in your place, I would have chosen IIIT Hyderabad. There are a number of reasons that support my choice.

• IIIT Hyderabad is a CS-oriented institute so follows a well-structured and CS-tailored curriculum. The curriculum is flexible and concepts are delivered in a dynamic way through classes, tutorials, labs, and assignments.
• IIIT Hyderabad conducts rigorous classroom sessions that ensure maximum student involvement. The concepts are not just delivered but taught thoroughly. Students have explained the logic behind everything.
• The lab sessions are usually taught by TAs who guide you and explain the practical concepts thoroughly. They help you overcome the major and minor problems in coding.
• Students are given very challenging problems in tutorials that help them improve drastically.
• The assignments are set excellently by the professors who want to keep the students one step ahead of the classes and prepare them for the exams. The assignments are discussed during tutorials to ensure everyone completes them without any problem.

In all, IIIT Hyderabad gives you a sense of freedom to explore yourself and your surroundings better. 

NSUT Delhi is known for its COE (Computer Engineering) course.

The COE course is different from CSE. In COE, you will study hardware, electronics & signals, and codes & algorithms. Unlike CSE, software is not the main focus of study in COE.

Now as far as a comparison between them is considered, IIITD has a much better teaching environment than NSUT Delhi. Though it also has an experienced faculty, you will mainly be taught by Ph.D. students during the first two years.

Unlike before, however, the NSUT Delhi curriculum has been updated. There is now a CBCS (Choice Based Credit System) and you won’t have to compulsorily study unnecessary subjects. Both institutes have a pretty good placement record. Although the COE branch concerns itself more with hardware, students get placed majorly in software profiles. 

All I can say is that NSUT Delhi has now an updated curriculum and a university status. On the other hand, IIITD is a comparatively new player in this field that is also performing quite well. Thus, both institutions are a good choice to pursue your computer studies.

My brother completed his CSE from NIT Bhopal. He does not know about the CSE at NIT Rourkela, however, here are his opinions about CSE at NIT Bhopal-

1. Faculty and Teaching Standards - The CSE faculty at NIT Bhopal is not up to the mark. If you are looking for a faculty to guide you and teach you everything, you will be disappointed over there. At NIT Bhopal, you will mostly be on your own. This can be advantageous in that you will get ample time to work on yourself and prepare well for your future.
2. Placements - The placement scenario for CSE is quite good at NIT Bhopal. Multiple companies regularly visit the campus for CSE placements and many new ones visit each year. Various companies hire CSE students for different positions. Companies like Amazon, Microsoft, Adobe, Deutsche Bank, JP Morgan, SAP, Factset, etc. visit the campus for CSE placements. During 2022, the average package for CSE students stood at INR 17.45 LPA. CSE students also receive internship offers during their pre final/ final year. These internships are of 2, 6 or 10 months and you may even end up with pre placement offers.

NIT Bhopal CSE has a good placement record but not the best faculty. I would suggest you consult the alumni from CSE branch at NIT Rourkela to get a clear picture of this institution as well before you can choose between the two.

I was in a similar dilemma last year, and ended up choosing BITS Hyderabad. My friends who chose top EAMCET colleges regret their decision at present. BITS does not only offer good academics, it also gives a lot of opportunities and exposure to its students.

If you are passionate about CS, then opt for a dual degree program at BITS, or CS at other colleges. But if you do not have a specific branch in mind, opt for BITS. Later on, you might want to switch from engineering to some other sector, like finance.

The clubs and departments at BITS Hyderabad will give you ample exposure to understand your interests and goals. Moreover, top investment banks, and companies from various sectors visit the campus with good placement offers every year.

BITS Hyderabad has a far better placement record and brand name as compared to EAMCET colleges. It has a rich curriculum, unlike the EAMCET colleges, which give all the importance to theory, and coding is not taught properly. BITS Hyderabad has a good infrastructure with lush green campus.

Thus, if you do not have a specific branch preference, I would recommend BITS Hyderabad over EAMCET colleges any day.
