Nirma University is better than LNMIIT as LNMIIT is a very new college as compared to Nirma. Secondly, Nirma university has been ranked 29 by MHRD. It is better both in terms of infrastructure and placements.

It totally depends on your choice of field. If you're interested in petroleum industry then you should apply for PDPU else Nirma University is the best choice. Most of the faculty at Nirma University are highly experienced. Faculties from IIM-Ahmedabad and other premier institutes visit IMNU for guest lectures. Nirma University also provides good industry exposure.

All the best.

Getting admitted to newly formed institution is of great risk, I don't know whether they will be good or not.
But, CSE of IIEST, Shibpur is a great department, be its students selected in Google Summer of Code or Linux foundation or be it Microsoft and Google placement offers. But placements are not all about the CODEIIEST society. It is also good which collaborates with Robotics Society -"ROBODARSHAN" or seminars.
It will surely develop and upgrade facilities in the upcoming years.

Admissions in NID, Gandhinagar is completely based on the entrance exam conducted by NID. One must clear the entrance exam and get an eligible rank. Though clearing class 12th exam is necessary as well.
