NIT Surathkal B.Tech in CSE is definitely a better choice because it's one of the oldest institutes with a rich legacy. The department has lots of establishments in academics as well as industry. There are several well-established student activity bodies and an elaborate alumni base with a coding background.

I am strongly against you joining an integrated program at the bachelor's level because you first need to know the exact domain you are interested in. If you realize that you have taken the wrong branch then spending 5 years will become very difficult. BTech gives you enough time and opportunities to analyze what your interests are you can not decide, after 3-4 semesters, you will be able to judge yourself overall. Also, a B.Tech in CSE from NIT Karnataka with a good GRE score may help you get admission offers of MS abroad.

So go for NIT Surathkal BTech in CSE without any second thoughts.

If you are considering pursuing a career in IT, here are some reasons why you should consider the Institute of Engineering and Technology (IET) at Devi Ahilya Vishwavidyalaya (DAVV) in Indore, Madhya Pradesh:

• The students, environment, and culture at IET-DAVV are better than other colleges in the region. The institute focuses on providing quality education and a conducive learning environment.

IEM Kolkata is better than Kalyani. If you are interested in branches like CSE, ECE, or IT, IEM will be a better choice. The placement record of the institute is a lot better compared to Kalyani. IEM Kolkata placements have the median CTC of INR 4.01 LPA.

Among JECRC University and Poornima University, the latter is the better option. There are many reasons for choosing the institute over JECRC. 

• Poornima University delivers quality education through a well-planned course curriculum. The faculties are well-experienced. They use a practical approach to teaching. Which helps students to understand the subjects better. 
• PU has a decent placement scenario. According to the recent placement highlights, the average CTC offered by the institute was 4 LPA.

My brother was in a similar dilemma when he got CS in Manipal as well as IIIT Delhi. After consulting a few friends at Manipal, he decided to go for IIIT Delhi. He stated the following reasons for choosing IIIT Delhi over MIT Manipal.

1. Selection Criteria : Manipal selection criteria a relatively easier selection criteria than the JEE Main + CBSE criteria IIITD uses. There isn't any kind of negative marking and focus is given to the English language. Thus, the crowd may not be as talented and intellectual as IIIT Delhi.
2. CSE : I wouldn't be exaggerating if I said IIIT Delhis CSE program is at par with the IITs. The faculty is highly qualified and the curriculum is very dynamic. The first year is branch-specific and does not have common subjects.
3. Higher Studies : IIIT Delhi students are exposed to some of the best research and projects. The faculty's Letter of recommendation can help shape your career for the better.
4. Placements : IIIT Delhi does not have mass recruiters and very limited non-tech companies. The overall placement stats are excellent.

If you want laid-back academics with a vibrant campus life, your choice should be Manipal whereas if you want a rigorous curriculum, then go for IIIT Delhi. It’s just a question of what your priorities are.

ISM Dhanbad got the IIT tag a few years back. 

It offers pretty good placements and research facilities. The campus is well-maintained and of decent size. It is being further improved and even has its own mall now. Other than that, the college has a fully centralized air-conditioned technical library- the largest in Asia.

IIT Dhanbad is at par with the old IITs. It is the best college in India for Earth Science branches (Mining, Mining Machinery, Applied Geology, Mineral, etc). Other branches have also developed in recent years, especially since ISM has received the IIT tag.

This institute has one of the largest alumni networks in the public sector. It has an MHRD-funded faculty development centre, which is one of its kind in the entire country. It is constructing a Central Research facility within its campus, in collaboration with Australian universities, as a result of an MoU signed by PM Modi during his visit to Australia a few years back. Many centrally funded projects are also taking place within the campus.

So IIT Dhanbad is far ahead of new IITs and at par with the old ones.

IIIT Gwalior is better. It offers superior facilities and infrastructure. IIIT Gwalior placements are better as well. It attracts many major industry recruiters to the campus drive. During the 2022 placements, the average and highest CTC offered were INR 24.85 LPA and INR 1.95 CPA, respectively. The recruiters' list included names such as Dell, Microsoft, Facebook, Google India, etc.
