Had you asked this question 4-5 years ago, the common answer would have been Thapar University. However, things have changed a lot in the last few years. Here are some reasons why I would suggest you to go for JIIT Noida for your B.Tech CSE-

1. The crowd quality at Thapar University has gone down drastically. The reasons behind this are a 50% quota for Punjab students and the enormous increase in the number of seats. Both these actions have resulted in very low cut offs. The cutoff rank for Punjab students in JEE Mains is 1.5 Lakh+ for CSE department. The closing rank of JIIT Noida for the same is around 51 K+. Thus, the crowd is better in JIIT Noida as compared to Thapar.
2. The batch size at Thapar University is much bigger than JIIT N. Thapar University has a batch size of 1200+ students for Computers while JIIT Noida has a batch size of only 250+ students. A smaller batch size means more placement opportunities and better attention towards the learning of each student.
3. Location-wise, NCR offers more opportunities than Patiala. You will get numerous opportunities in NCR like trade shows, conferences, training, better placements, etc. Gurgaon and Noida are the new IT Hubs, second only to Bangalore and at par with Hyderabad and Pune. As a CSE student, you should prefer Noida over Patiala. 
4. Though Thapar University has a bigger campus of 250 acres, your life will mostly revolve around your classrooms, nearby areas and your hostel. Thus, the smaller campus of JIIT N should not be that big an obstacle.
5. The average package for B.Tech CSE is around INR 13.28 LPA at JIIT Noida, which is better than Thapar University in which the average package for the UG stream stands at around INR 10.97 LPA. Studying at JIIT Noida is also around 30-40% cheaper than Thapar.

Thus, at present, CSE from JIIT Noida is a much better choice.

I am a CSE student at IIT Patna and I will try to justify why choosing IIT Patna for your

CSE is a good decision. Don’t base your choice on how old an institution is. 

All the new IITs like IIT Patna or IIT Jodhpur are doing exceptionally well, some are even competing against the old IITs. IIT Patna has a great campus and it has achieved tremendous success in a short span of time. 

CSE department has a learned and supportive faculty and great seniors. The teams have always performed exceptionally well in the ACM-ICPC and have even made it to the world finals. A good number of students clear the  GSoC( Google Summer of Code). 

NJACK club organizes tutorial classes and workshops on Web development, App development, Android, etc. It also organizes competitions like Capture the Flag, NWoC-an open source coding event, and other competitions throughout the year.

Other interdisciplinary teams which you can join are ROBOCON, Supra BAJA, HPVC etc. 

CSE alums at IIT Patna have made successful startups and others are working in good positions at top MNCs. Overall, the coding culture over here is excellent.

The placements for the CSE department are quite impressive. For 2023 placements, the highest package stood at INR 82.05 LPA. The average package stood at INR 35.57 LPA and the median package stood at INR 32.85 LPA. 98.65% of students from the CSE branch were placed.

In the end, whether you choose IIT Jodhpur, IIT Mandi, IIT Patna, or any other institution, the choice should be based on your personal preference. However, I would suggest you choose IIT Patna CSE as I am quite satisfied with my choice. 

There are many reasons why some students prefer CSE at NSIT to CSE at DTU. I have listed some strong reasons below:

• NSIT has a smaller batch size which in turn means the level of competition faced by the students is comparatively low. You can get good job profiles way more easily than at an institute with a higher intake like DTU.
• NSIT awards you a degree from DU, one of the most globally recognized and reputed universities. This helps you pursue higher studies in foreign countries easily. 
• Quite a few NSIT students are able to secure high packages in top companies like Facebook while DTU because of its large batch size has only a few that get 1 cr+ packages.
• One of the major reasons why someone would prefer NSIT over DTU is that it’s quite difficult to get a hostel in DTU especially if you are a resident of Delhi.

If you consider these reasons valid, go for NSIT instead of DTU.

The best way is to break down various components and analyze each parameter individually. 

Placements

• IIT Madras's average package in 2023 stood at INR 24.4 LPA while IIT Kanpur CSE highest package stood at 1.02 CPA.

Ranking

• IIT Kanpur was ranked 264th by the QS World University Rankings 2023 and #4 by NIRF for the year 2023 in the Engineering category whereas IIT Madras is ranked #1 by NIRF.

Campus

• IIT Madras has a 630 acres campus with many sports facilities like a gym, badminton courts, a swimming pool, and a cricket ground to name a few. The labs, library, and overall infrastructure are top-notch.
• IIT Kanpur is one of the biggest IIT campuses spread across 1000 acres. It has a dynamic campus life with many fests and activities. The library is huge and there is a club for everything.

Overall, IIT Madras seems to be in a better position than IIT Kanpur although both are excellent institutes of technical education.

Yes, irrespective of the branch, choosing IIT Delhi will always prove to be beneficial for you. IIT Delhi has ties with many big firms that visit the campus for placements and offer great packages irrespective of your branch. One needs to be proficient in DSA and other computer science core subjects such as OOPS, OS, DBMS, and Computer Networks. A good grasp of these will fetch you a high-paying job no matter which branch you belong to in IIT Delhi.

Although most companies that visit IIT Delhi also visit NIT, your IIT tag will always fetch you extra benefits and no one can deny that. For instance, the same role offered to an IITiand will have more salary than that offered to a non-IITian.You can easily switch roles and fields given the brand name of the institute you are associated with. IITians even have more opportunities for higher studies in Foreign countries than non-IITians.

IITians especially from Mumbai or Delhi are always given preference over non-IITians hence it is advisable to go for IIT Delhi in any branch.
