Hello, I hope you are doing well

NSUT MPAE is a a good branch to study and the course curriculum for this branch is quite decent than other Mechanical Engineering courses. Yes, the placements are not quite good in MPAE when compared with tech branches, but it is still decent. Moreover you can try coding and if you make your mind to go in tech field, then NSUT is any day better than IIIT Una. The coding culture, peer group and Seniors at NSUT are very good. You will be allowed to sit in 50%-60% of the tech companies for placement. The campus is located in Dwarka, heart of Delhi. So, there are tons of places to hangout after the college.

IIIT Una ECE has also good curriculum and faculty, the campus is located in Una, Himachal Pradesh. The Lab facilities are quite impressive, but IIIT Una gets beaten by NSUT when it comes to the placement scenario. The highest CTC  at IIIT Una ranges around Rs.13-14 LPA. NSUT has an average package of around 16-17.5 LPA in tech field.

So, you should go for NSUT MPAE.

Hope this helps.
