I pursued my B.Tech Mechanical from SVNIT, thus, I can only comment on my college.

The faculty of the mechanical department is top notch. Majority of our teachers are highly driven. It is because of them that mechanical is the most famous branch of our college. Our teachers emphasize practical knowledge over mere theoretical understanding. Many of them have more than 10 years of experience in teaching. The department has enough professors, so very few courses are taken by TAs. The faculty is very helpful for projects and research work.

The curriculum for B.Tech Mechanical is very rich, and you’ll get to choose one elective per semester in the 3rd and 4th year. You can choose courses from other branches as well. You can choose management courses, programming courses, physics related courses, automobile courses, etc. SVNIT is probably the only college that teaches its students topics like Mechatronics, Computational fluid mechanics (CFD), Cryogenics, etc. at the UG level itself. 

Unfortunately, like most other colleges, our practical syllabus and lab equipment needs to be upgraded. The labs do not contain equipment of the latest technology. The workshop contains all conventional and non conventional machines like lathe, shoper, milling, grinding, welding, abrasive jet machine, EDM, 3-D printer, etc.

As far as B.Tech Mechanical at SVNIT is concerned, I would say it is quite a decent option.

Honestly speaking, BIT Mesra is nowhere near the IITs and top NITs. It can however be compared to other NITs like  NIT Rourkela, Jamshedpur. Surat, etc.

The institute is known to have excellent campus facilities but the opportunities in core branches are limited. BIT Mesra is a brand name well-known among private colleges. It can be compared to the new IITs to a little extent and is even better than VIT and Manipal University. The only drawback is that getting a high GPA here is quite challenging. 

Nevertheless, BIT Mesra is a decent choice for many if you consider the following points 

• It focuses on the holistic development of its students and hence has a number of clubs that help students pursue their passion alongside academics 
• BIT Mesra offers a plethora of opportunities and exposure to its students.
• The institute is well-known for its excellent coding culture and thus attracts many IT companies during placements.
• The Institute does not tolerate ragging in any form. There is a strong bond between the juniors and seniors.
• The campus spreads across 780 acres and is surrounded by lush greenery.
• The institute has an amazing placement record and last year the highest salary stood at INR 58.33 LPA while the average salary stood at INR 13.01 LPA

Ultimately, BIT Mesra is better than most NITs but not at par with IITs and a few top NIT.

NIT Rourkela has very good infrastructure, placements, rankings and facilities. It has a legacy of its own. But it can not be compared with NIT Trichy as of yet. Perhaps a few years down the line, Rourkela will reach the level of Trichy. But as of now, Trichy is the best among all NITs. NIT Trichy has much higher placement stats than NIT Rourkela. 

You should choose NIT Rourkela over NITT only if you get a very good branch or a core branch at the former, and a not so good branch at the latter.

Yes, IIT BHU is better than IIT Indore in terms of infrastructure, alumni base, research exposure. 

• At IIT BHU, old departments like Mechanical, etc. have old machines and lab equipment. But departments like CSE, Mathematics have new buildings, computers, etc. 
• IIT BHU also has the advantage of a larger alumni network. 
• It offers marginally better placement opportunities in core branches. 
• The research culture is quite active on campus, especially for different fields of CSE like Machine Learning, Computer Vision, etc. 
• The faculty base of IIT BHU is good, similar to any other old IITs.
