Both institutes are relatively new and enjoy a similar status and brand value in the education world. IIT Palakkad is a new IIT while IIT Dhanbad although an old institution has recently been given the IIT title. So that leaves us with preference as the major factor in determining which institute is the right one for you.

MNC is a blend of both Math and Computing concepts and is often very rigorous. The mathematical proofs and theorems form a major part of the curriculum and CS comprises just a minor portion of it. Unless you are a math lover or are genuinely interested in it, this branch might be very challenging for you as the concepts are very advanced and nothing like what you studied before. CSE on the other hand is an evergreen branch with broad prospects. 

Moreover, the faculty of IIT Palakkad are from IITM also thus improving the quality of education offered. The infrastructure is excellent with great accommodation facilities.

IIT (ISM) Dhanbad although a new IIT, has a rich legacy of being one of the oldest technical institutes in India. It is considered even better than some old IITs and obviously better than the new ones. IIT Dhanbad has an outstanding placement record thanks to its extensive alumni pool. Consider the following placement statistics for a better understanding

So choosing IIT Dhanbad over the new IIts will be a better decision on your behalf.

All three colleges, IIT Dhanbad, IIT BHU, and MNNIT Allahabad, are well-reputed and offer quality education in their respective fields. However, the choice between the three ultimately depends on your personal preferences and career goals. Here are some points to consider:

IIT Dhanbad (CS):

Pros:

• One of the top-ranked engineering colleges in India.
• Strong faculty with research expertise in various fields of Computer Science.
• Good industry collaborations and placement opportunities.

Cons: Relatively new compared to some of the other IITs, so may not have as established an alumni network.

IIT BHU (Electrical):

Pros:

• One of the oldest and most prestigious engineering colleges in India.
• Strong faculty with research expertise in various fields of Electrical Engineering.
• Good industry collaborations and placement opportunities.

Cons: As an Electrical Engineering program, it may not have as many opportunities to specialize in Computer Science.

MNNIT Allahabad (CS):

Pros:

• One of the top-ranked NITs in India.
• Strong faculty with research expertise in various fields of Computer Science.
• Good industry collaborations and placement opportunities.

Cons: May not have as established an alumni network compared to the older IITs.

Based on the above factors, it would be recommended to consider IIT Dhanbad (CS) as the best option among the aforementioned colleges.

IIT Dhanbad is best for pursuing mechanical engineering. It provides students with top-notch academic resources and amenities. Additionally, the placements are fairly decent. Every year, between 70 and 80 percent of students in the mechanical stream get placed. The former is better IIT Dhanbad was established in 1926 whereas IIT Jodhpur came in 2008. In terms of placement, faculty, ranking, and academic excellence IIT Dhanbad stays in the upper hand for pursuing mechanical engineering than IIT Jodhpur. The reasons for choosing IIT Dhanbad are as follows:

• Ranking and reputation: IIT Dhanbad was rated 17th among the finest engineering schools in the country in 2023, which is a reflection of the school's academic performance, resources, faculty depth, etc.
• Faculty : All of the faculty members are intelligent and welcoming. They are extremely knowledgeable in their fields. Their course syllabus is appropriate for students who are interested in working in the core industry in the future.
•  Placement: About 70-80% of students are accepted for campus job placement in IIT Dhanbad. The average package ranges between INR 16-17 LPA and the highest package is around INR 56 LPA.
• Alumni Network: At IITs, there is a high prevalence of robust alumni networks, which may be helpful for networking, job placements, and internships. Vinay Kumar Dewan, the founder, and chairman of Bramco Group, is a native of Bahrain. operations in the Middle East, India, Germany, the UK, and the United States); Dr. Ganesh Thakur, vice president of Chevron Corporation in the United States; and Dr. Mihir Sinha, an authority on energy financing. IIT Dhanbad is home to a number of famous people, including the former vice president of J. P. Morgan in the United States.

In conclusion, IIT Dhanbad would be a great place to study mechanical engineering. With its long-standing reputation, knowledgeable faculty, employment opportunities, and a campus that is well-equipped. It cultivates a setting that is advantageous for both academic and personal growth.

Irrespective of the IIT tag you go for, Civil Engineering always has limited placements. Civil Engineering has become an outdated branch with little or no scope left. Although there are people who go for various options after pursuing civil engineering, which may include UPSC Examinations. What I mean is that Civil Engineering is not the right choice if your goal is placements. In that case consider ECE from ISM Dhanbad. Owing to the increased research in Machine Learning, the ECE branch is expected to grow ten folds in the coming future. 

Additionally, ECE in IIT (ISM) has a pretty good coding and robotics culture, so you have both options, going for core jobs or CS jobs.

Ultimately, it’s all about personal inclinations. All I suggest is that never go for a mediocre rank just because a certain IIT is better than the other. The choice of your branch is equally important as the choice of your institute. Moreover, the Civil engineering scenario is similar in every IITs.
