which is better NIT Trichi Mechanical or BITS Pilani Manufacturing ?

Hello aspirant!
Many answers above have very well summarized the points on which distinction can be made. But the most important difference according to me is that of culture. Culture in BITS is simply amazing with a hell lot of opportunities for personal growth. Also, the level of fests and campus life which BITS offers is pretty unique and difficult to get at NIT TRICHY. So if you have the resources BITS can be ur first preference. Also an important thing considering the ever important question of Placements. At BITS most of the companies would you treat u at par with IITs( I know of Bosch, GE because of my background) which I don't believe can be the case with NIT TRICHY.
Both NITs and BITS have quality infrastructure because they are one of the world's prestigious technology institutes. However, BITS might have a slight edge as it is better equipped to meet the growing demands of students. BITS is also well staffed because the number of students are less in comparison to NITs.
Nevertheless both institutions are good it depends on you what you wanted to prefer.

Hope this information will help you!

Thank you!
