BITS Pilani is located in Rajasthan, which is and used to be a part of India's so-called active north. As a result, BIT Mesra is not preferred by the people of the north, who have better options of IITs and NITs. While some go for the south. It is only an ideal place for Bihar, Bengal, Orisha, Jharkhand, and the neighboring state.

BIT Mesra was ranked 7th by India Today Group Survey, but it remains isolated in terms of fame because students are the biggest marketer for a deemed institution. If you say, “Hey, I am from Bit Mesra,” the likely answer would be, “Is it a subsidiary unit of Bits Pilani?” As BITS Pilani is more reputed. 

Here are a few other reasons why BIT Mesra has not gained much recognition among the students. 

• The kind of behavior carried or promoted among teachers is more akin to a school teacher, so the title professor is unnecessary.
• The management approach at BIT is very bad; there is a lot of paperwork to be done for any minor thing. From the time you enroll until the day you leave the campus you will have to go through many paper works.
• Off campuses are given no value by the main campus, and this is a major reason why BIT is not mentioned with off campuses. Whereas Pilani has four centers that are advertised, in very good condition, and are given true care by the Pilani main campus. This is a major reason why Pillani is more well-known than Mesra. 
• There is no student council or student politics, and no student welfare council composed of fellow students exists or is promoted.
• Apart from these, the governor of Jharkhand, who is only present at convocations, is the chancellor of Mesra, while Pilani is completely managed by the Birlas, with MR Kumar Mangalam Birla as the chairman.
• Another major reason for Pillani's success is the engineering entrance exam pattern. BIT Pilani organizes a separate exam called BIT SAT, whereas BIT Mesra does not take any separate exam.

This all that I have learned through my connections at the institutes. Hope this helps in clearing your doubts. 

A friend of mine is currently studying in the 2nd year at IIIT Guwahati and recently shifted to the new campus. However, the campus is still getting completed with minor changes remaining. 

Here’s the current scenario at IIIT G according to him:

• Gym: It is almost completed with basic types of equipment and benches. For the starting few semesters there were no machines and equipment. However, you can also join various gyms nearby the airport which is in close proximity to the college.

• Playgrounds: You will see a lot of emphasis on sports and games, not only the outdoor but indoor like table tennis, carom, chess, etc. There are newly constructed basketball, tennis and badminton courts, football and cricket fields also.

• Intercollege tournaments: You can actively participate in various sports/game tournaments and competitions held by clubs where you can compete against other colleges like IIT Guwahati, AEC, etc.

• Clubs: You can choose among several clubs, some of them are Reading Club, Programming Club, Music Club, Quiz Club, Literary Club, Movie Club, Yoga, and fitness Club, Dance Club, Photography club, etc.

There are ample opportunities for extracurricular activities besides academics. Also, the recent increase of intake from 90 students to 230 students has led to a significant improvement in these fields. In the end, your interest and participation are what drives the campus.

IIT Gandhinagar is the only IIT among various other semi-new IITs to have entirely shifted all its premises into its own campus. 

• IITGN is privileged with an afresh 21st-century campus, which is popularly facilitated with all the major necessities. Besides, it also is benefited with enough infrastructure that can weigh up to catering to more than its current magnitude of students as a whole.
• The new campus of the institution has both capacious classrooms, and small classrooms alongside huge auditoriums, offices for staff members, professors, and faculty employees all anew. 
• Alongside those spacious rooms, it also has newly made 6 hostel buildings and 2 messes with various modernized equipment like wifi routers, smoke detectors, and more devices alike. 
• The institution has a gymnasium, basketball court, cricket ground, volleyball court, temporary athletics track, TT room, and a football ground as well. There are things other than these which students can explore once they visit this vast campus.

Thus, as per your question concerns, IIT Gandhinagar has both facilities and infrastructure at par with other world-class institutes and is yet under development to become better.

One of my friends studied at IIM Udaipur and here are some facts he mentioned, which might help you get to know it a bit better.
