NIT Silchar is one of the top engineering colleges in India. Recently in NIRF Ranking by MHRD, NIT Silchar holds 46th rank among best engineering Institutes in the country.

My brother is from NIT Silchar and this is the best thing that ever happened to him. But also every institute has its own advantages and disadvantages.

Pros:

• Weather: Pristine green and calm climate, No pollution, Beautiful lakes, and amazing tea gardens.
• Professors: The teachers here are extremely friendly. They will advise you on your future choices and point you in the right direction.
• Other Activities: Apart from your academics, you have the freedom to explore your hobbies or create new ones, develop other skills, go on a tour to nearby amazing places like Mizoram, Shillong, Sikkim, Twang, and so on. 
• Internet: The best thing among all facilities is unlimited internet access. Many colleges have high-speed internet, but they do not provide unlimited access without a time limit.
• Placement: Many notable companies visit the campus every year for good placements like Samsung, Goldman Sachs, L&T, Flour Daniell, Snapdeal, Gammon, BPCL, HPCL, Reliance JIO, etc.
• Start-up Culture: NIT Silchar has recently established a startup center under the Government of India to promote entrepreneurship among students and in surrounding areas, with the goal of being a Job Creator rather than a Job Seeker. 
• Festivals and Celebrations: All the festivals are celebrated on college campuses like Diwali, Bihu, Holi, etc. This college also organize cultural fests every year such as the Technical festival — Tecnoesis, Cultural festival, Incandescence and Posua, Management festival, Paarbon, Innovation festival.

Cons:

• In-time for girls: Girls are not allowed to go out after 8 P. M.
• Food: Be it mess or canteens or restaurants in the city you will crave good food. People will tell you about a few restaurants for their amazing food, but they will not tell you about their food serving time. But if you have Subway on your campus then there is no problem.

I hope my answer is helpful to you.

When I asked a senior of mine the same question, she told me to exclude NIT Raipur. The reason is, NIT Raipur is one of the newer institutes and to be considered worthy, the institute has to improve a lot.

The other two institutes, however, would be a tough call.

My senior said BIT Mesra is slightly ahead of NIT Hamirpur just because the former has been around for much longer than the latter.

Despite all that, NIT Hamirpur is located in pleasant surroundings. In addition to that, it will also give you the NIT tag and is an INI. So, in the case of comparison by merit, it all depends on who has the higher cut-off in a particular session.

NIT Hamirpur is also a new NIT and it is improving with each day. On the other hand, the quality of education, placements in the electrical branch of NIT Raipur are going down with each passing day.

My brother is from PEC Chandigarh, so I might be able to share some facts with you. Some important factors regarding placements of PEC include the following:

• PEC has an academic policy that requires you to complete a 6-month internship in an industry or a research laboratory during the fifth semester. It strengthens the industry-academia relationship while also securing good PPO. This policy does not apply to NITs.
• PEC's alumni-institution relationship is one-of-a-kind because of its long history. Try to construct it at NITH so that in upcoming days it'll be fruitful.
• A dedicated Career Development and Guidance Cell (former TPO) is required to contact and invite large corporations to the campus.
• With the practical approach to teaching and the freedom to participate in extracurricular activities, PEC students have a lower academic load than NITH students.
• The final but most important factor is the ability (not to be confused with talent) that the students develop here being a part of a club or society.

Above all, study hard to gain good core knowledge, use your nit tag, and try to land good off-campus placement offers. This will certainly change the atmosphere on campus and your college's image in the eyes of industry. The change will come gradually with time.

My friends have been studying in both NIT Hamirpur and PEC Chandigarh and according to their first-hand experience, PEC Chandigarh holds an edge. Here’s why:

• It lies in a prime location viz. Chandigarh. The city has better and numerous opportunities. It is an education hub in the North, hence making it easier to plan and implement your higher education goals. There are ample coaching centers as well in case you want to prepare for government exams.

• PEC has better placement and internship options as well, again it is due to the location advantage.

Overall, while both the colleges offer good education, NIT holds a big brand name. However, factors like location and opportunities come first when in such a dilemma. Also, as you are getting the same branch in both the colleges, choose PEC Chandigarh any day.
