Amity Noida is better for CSE. It is the oldest campus and offers better facilities. The placement scenario for CSE is comparably better at Amity Noida. Major industry giants such as Microsoft, Accenture, IBM, L&T Infotech, etc. take part in the campus drive. Amity Noida placement highlights show the average package for CSE to be around INR 5 LPA. While the highest CTC offered goes up to INR 26 LPA. 

IIT Roorkee, NIT Trichy, and NIT Warangal are well-established institutes in India. The scope of metallurgy is comparatively lower than that of CSE. IIT Roorkee mainly concentrates on textual learning and does not give the students exposure to practical learning. They are using the practice of mugging up the lessons without having a clear understanding of the topic. The placement is very poor here; the students from the metallurgy department usually end up in data analytics and coding.

So CSE at NIT Warangal and Trichy would be a better choice.

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.
