Which one should I choose, IIIT Allahabad (IT), MNIT Allahabad (IT), NIT Bhopal (CSE), or NIT Jalandhar (CSE)?

IIIT Allahabad is better than MNIT Allahabad if you are interested in coding. Although NITs and IIIT Allahabad both are centrally funded technical institutes. The only difference is the course curriculum as IIIT Allahabad focuses only on IT and ECE. Due to this, minor subjects like Chemistry, Applied Mechanics, Engineering Drawing are dropped in 1st and 2nd semester itself. 

NITs have a long legacy making it more reputable with strong alumni across all domains. On the other hand, IIITA is a young institution and follows innovative academic policies. Its alumni members are even present in Silicon Valley in a short span of time.

You can decide your own priorities in the career. If you are interested in coding culture and look forward to great internships and placements with a small cozy campus, you should prefer IIIT Allahabad. You should opt for MNIT Allahabad if you are interested in meeting new people with diverse backgrounds. It will help you in enhancing your personality. 

If you ask me, my vote goes for IIIT Allahabad on all these below parameters.

• College Life: IIIT Allahabad is an institute of national importance, and boasts one of the best campuses in the country. Whereas, MNNIT is not even on the edge.
• Placements: 96% of the students got placed and received job offers from more than 120 companies. All major Computer Science companies like Google, Facebook, Amazon, and Adobe come to IIIT Allahabad's campus and make offers.

The following table shows the placement statistics of IIIT Allahabad:

IIIT Allahabad has placements in Google Mountain View/ Europe/ Australia/Japan from almost every Batch from the past 4-5 years. IIIT Allahabad was preferred by these companies because a lot of alumni already worked in these companies and better industry perception has been built up.

The strength in NIT-A is approximately twice as compared to IIIT-A. And every year this strength keeps increasing. As you know that the quality decreases with the increase in strength, I would again suggest you choose IIIT-A.
