My friends passed out from IMT Ghaziabad and said that your specialization does not really matter. What matters is the institute. She was in a dilemma about choosing IMT and TAPMI and later went for IMT Ghaziabad and is very proud of her decision. She thinks it has many advantages over TAPMI like

• IMT Ghaziabad has a better reputation and brand name than TAPMI
• Most recruiters consider IMT a top B School of the country and give it preference to TAPMI
• IMT does not instill unnecessary rigor and has a calm relaxed environment. It’s up to you to grab the necessary opportunities and climb the ladder
• The campus life is usually student driven so it helps in overall personality development
• The Operations faculty at IMT Ghaziabad is a notch above TAPMI

All these points clearly show that IMT Ghaziabad is better than TAPMI.

The choice of both branch and institute depends a lot on factors like your career prospects and areas of interest. However, since you haven't decided on a branch yet, I will assume you aren't yet sure of a branch and are open to exploring more branches. Don't worry, as most students clearing JEE Advanced face a similar situation. Personally, I will recommend you to go for IIT KGP over ISM Dhanbad because of 2 strong reasons
IIT KGP gives you the chance to explore and identify your area of interest. Even if you go for coding and later realize you don't like it, you can always go for non-core jobs that are in abundance at IIT KGP. But in the case of Dhanbad, you will have to stick to coding irrespective of your career inclinations. This is a major factor as it is your passion that determines your success rate.
IIT KGP has a more diverse group of individuals that are literal geniuses. Even if you are an above-average student you will face tough competition and thus will always strive to excel and grow. Dhanbad has an average-quality peer group and thus your growth might be restricted there.
I can only guide you to make a good decision, the final authority lies with you.

The five-year IIM Indore IPM degree combines undergraduate and postgraduate management courses. Students who want to start their management career after 12th grade should take this course. The programme comprises economics, accounting, marketing, and human resource management classes and internships with prominent organisations. This management programme is well-regarded and offers great job chances.

BMS at Xavier College Mumbai is a three-year undergraduate programme that covers all elements of management. This programme teaches management skills. The programme offers internships, economics, statistics, marketing, and finance classes.

Both degrees are well-regarded and provide great managerial careers. IIM Indore's IPM programme may be a fantastic choice for 12th-graders who want to start their management careers. The BMS programme at Xavier College Mumbai may be preferable for you if you desire a more conventional undergraduate education and then management.

It is hard to compare particularly the finance stream but overall comparison is given below in the table;

Rather than giving you a direct answer, I am going to evaluate all The aforementioned institutes individually on the basis of some common parameters like placements, brand name, campus life, opportunities, and alumni.

IIT BHU ECE

• Core placements are rare and students mostly build their profile for software development companies by becoming proficient in various programming languages, doing competitive coding, doing projects, and trying to build a computer science-inclined profile. A handful of students target core engineering roles.
• The brand value is similar to other colleges mentioned
• The campus is rather old and might disappoint freshers expecting a good college life.

IIT Guwahati ECE

• Unfortunately, I have no knowledge about this Institute. However, I recommend you contact the seniors of IIT Guwahati for the same.

IIT Hyderabad Maths and Computing

• Usually, MNCs attract top-tier software and financial services firms. If you are a hardworking student, it wouldn’t be difficult to secure amazing offers at top firms.

IIIT Hyderabad CSE

• IIIT H has possibly one of the best computer science departments in the country. 
• You have to do core computer science courses right from the first year.
• Many students get selected for Google Summer of Code and IIIT Hyderabad has its alumni in top-notch firms. 
• Being highly academically oriented, IIIT Hyderabad has minimal campus life and extracurricular activities.

Ultimately, it’s a matter of preferences and what you are looking for in your degree.

As a student of UIET CSE, I will share some merits and demerits of the same with you-

Merits-

1. If you are a good coder, UIET offers decent placement opportunities in the CSE branch.
2. There is a 24*7 library facility.
3. You’ll get the ‘Panjab University’ tag. 
4. It is located in Chandigarh which is a serene, beautiful, and well-planned city.
5. Your personality and leadership qualities will improve.

Demerits-

1. The teaching environment isn’t good. You’ll have to learn by yourself, regardless of branch.
2. The tag of ‘IITs’ or ‘NITs’ holds much more significance.
3. You might not get the desired placement. In that case, you’ll be sitting for some competitive exam. For a placement in 4.5-5 LPA slab, you’ll have to work hard.

NIT Patna IT is a good option because it offers good placements and an NIT tag. As far as IIIT Bhubaneswar CSE is concerned, you can check all the information related to it and compare it with the other two.

Both IIIT Allahabad and MNNIT are highly regarded engineering colleges in North India offering premium quality education. Placements-wide, MNNIT CSE is slightly better compared to both NSUT and IIITA. In my opinion, the preference order should be

MNNIT CSE >= IIITA IT > NSUT CS/AI

MNNIT is the first choice because it’s on Eid the top 5 NITs with the most sought-after branch CSE. IIIT Allahabad is also a great choice for CSE because it has a CS-tailored curriculum and ambiance. 

Overall I feel if you are certain of joining an IT company, and have an interest in coding and computers go for IIIT Allahabad IT or MNNIT Allahabad. If you are unsure of your branch preference go for NSUT.
