Anyone getting admission to any IIT should not consider NITs then. It’s true that the old IITs have better infrastructure and brand value than tier-2 IITs but these new IITs are still in their development stage and haven’t reached their conclusion. Considering their huge growth over the past decade, they will reach new heights in the future

The new IITs provide better opportunities and freedom to students as the foundation of the college isn’t very strong so they build it alongside. The students grow and develop their personalities along with the growing institute. There is no compromise in the quality of education as the faculty is recruited after tremendous filtering. 

The branch is more important than the college so don’t choose a less preferred branch in an old IIT just for the brand value rather go for the branch of your choice in a new IIT.

As for Physics, it requires genuine commitment and interest. Go for it only if you are certain of a career in it as the options in this branch are limited in contrast to Electrical Engineering. That being said, IIT Ropar is one of the best second-generation IITs, and its curriculum is very flexible and the location is also great. So my final recommendation would be to go for IIT Ropar Electrical.

It’s illogical to compare two programs as the choice of branches depends on individual preferences. I will share the limited knowledge I possess for IIT Hyderabad CSE.

• IIT Hyderabad CSE department is very dynamic and rigorous. 
• The CS department has excellent professors that are very learned and experienced.
• The student crowd comprised good quality students most of them being top rankers. There is tough competition between peers maintaining the dynamic academic environment.
• The average package for CSE in IIT Hyderabad is the highest of all the other branches, with many international offers too.
• As far as higher studies are concerned, if you plan to do an MS abroad, every year a lot of students get admitted to highly reputed foreign universities like Stanford, UIUC, Georgia tech, and ETH Zurich.

Since I have no information on IIT Guwahati, I recommend you contact a senior and discuss basic details.

To make the best choice, I have entailed the pros and cons of both the institutes 

IIT Guwahati Pros

• A very established and beautiful campus that is on power backup

IIT Guwahati Cons

• Less academic flexibility in choosing courses
• Locational disadvantage results in less exposure to expert lectures 
• Major issues related to connectivity with high airfare
• Professors are very less motivated in delivering quality lectures due to lack of motivation.

IIT Hyderabad Pros

• Locational advantage results in better connectivity and excellent exposure to industry and experts
• More academic flexibility owing to the fractal academics
• Young and enthusiastic faculty members who have great experience and conduct top-notch research 

IIT Hyderabad Cons: 

• The permanent campus is still under construction.
• Relatively hot climate.

IIT Guwahati should never be your first choice and IIT Hyderabad is a much better option.

My brother was in a similar dilemma last year when he had to choose between MnC IIT Guwahati and CSE IIT Indore. Eventually, he went for IIT Indore CSE. The main reason he decided against going for the MnC program was his lack of interest in Math. And when we talk about Math at IIT, trust me when I say it’s at another level. It’s purely proof-based and high-level Math that can be handled only by true Math lovers. The academic workload is also high with 60% Math and 40% CS courses.

Now, here are a few points that might convince you to join IIT Indore instead

• IIT Indore qualified for ACM-ICPC World Finals thrice. This in itself is quite an achievement considering this event's importance.
• As per HackerRank, IIT Indore is said to have the best coders in the whole country. Additionally, it’s at the 8th position globally for the best coders
• IIT Indore has an extensive alumni base who completed their Master's from top foreign universities like Stanford, Caltech, University of Columbia. Many talented alumni also increase the credibility of the institute by working at reputed firms like Google and Facebook.
• This year, the CS department recorded 100% placements with the highest and average packages standing at INR 48.5 LPA and INR 30.32 LPA respectively.

Overall, IIT Indore CSE is a much better choice than MnC IIT Guwahati considering the work of and job opportunities.

One of my friends was doubtful whether the hindi-speaking culture of MNNIT will have any impact on her English communication skills. If you are doubtful regarding the same, I would say you need not worry uselessly. 

Students from MNNIT clear CAT with good scores. This wouldn’t have been possible without clearing the CAT verbal paper. Students converse in Hindi on campus simply because most of them belong to North India. This won’t have any negative effect on your English proficiency. Also, the professors deliver lectures in English. Other than that, to keep enhancing your English skills, you can join the English Literature group of MNNIT. 

As far as your options are concerned, MNNIT is known for its top notch education in CSE. It is one of the best colleges in India for a CSE program. Also, the placements offered at MNNIT are quite impressive, especially for its CSE branch.

According to me, you should choose CSE at MNNIT over IT at NIT Surathkal.

Let me share with you some important details about these courses/institutes-

1. NIT Durgapur is a residential campus so you’ll get ample exposure during your undergraduate studies. On the other hand, JU doesn’t even offer IT on its main campus.
2. NIT DGP is an Institute of National Importance. This makes it more significant on a national level.
3. NIT Durgapur is seeing a growing number of recruitments in its CSE branch. Startups visit the campus with interesting offers for CSE students.
4. The student community of NIT Durgapur is more diverse.
5. NIT DGP has no political interference. JU, on the other hand, is heavily influenced by state politics.
6. In terms of extracurricular activities, JU is a better choice.
7. The CSE/ECE departments of NIT DGP lack good infrastructure, have inconsistent course structure and content, and have a low teacher-student ratio. These departments lack quality research work.
8. Phd.s in the CSE department of NIT Dgp are low in number.
9. But NIT DGP carries the much-valued ‘NIT’ tag.

That being said, I feel you are at a very early stage of narrowing down your goals and aspirations to this extent. Enter your UG with an open mind, and an aim for self-discovery. Right now, you have a picture in mind of doing an MBA. But I don’t think you have a proper idea of the different specializations in this degree. 

You should have made a clear decision by the end of your 3rd year. Before that, pursue internships and discover your field of interest. Right now, look for the institute that will offer you the best technical education and the best future prospects.

Honestly, there isn't any major difference between CSE and IT branches as both are related to computers. The job opportunities are almost similar. So, you should prioritize college over branch in your case. NIT Surathkal is much better than MNNIT Allahabad and this can be further understood through the points below

Location: NIT Surathkal has an advantage over NIT Allahabad due to its location near Bangalore, the IT hub of India. Most Bangalore-based companies firstly visit NITK Surathkal. Last year major companies like Microsoft, DE Shaw, Uber, Amazon, Oracle and visited the campus last year.

Coding Culture: Recently 23 students from NIT Surathkal were selected for Google Summer of Code (GSOC) which is 4th Highest in the World. It has secured 13th Rank in the ICPC Asia Contest which is the highest ranked of all NITs. NIT Surathkal is the only single NIT that became a finalist in the ACM ICPC World Contest.

Academics: Every year students win International awards proving that their academics are better than MNNIT Allahabad. 

Campus Life: The campus life of NITK Surathkal is also better than NIT Allahabad as NITK Surathkal has a private beach with a lush green campus of 300 acres and its fest Incident is the largest Cultural event in South India

Placements: Refer to the table below for comparison of placement statistics

In all, NIT Surathkal seems to be a much better option than MNNIT Allahabad after considering various factors.
