Hi, Harsh.

This will be a personal opinion based answer so feel free to not pay any heed to it and keep your search going.

All the 4 colleges that you have named are average Engineering colleges with almost the same pros and cons shared amongst them. The question then becomes how to choose one to be better than the rest?

- Look at your travel convenience

- Look at the college placements

- Look at infrastructure

going in that direction I'd not suggest Ambalika Institute as very little information about it is available online which is always a dangerous sign.

the best reviews and ratings that go to IIMT, and ITS (ITS is rated NAAC 'B', these ratings are always average for colleges that lack good student bodies, internships and overall semester results)

but they both have really average placement opportunities and okay-ish faculty.

As for IILM, it is the most balanced college for the bunch- everything here is above average (3-5 lacs/annum avg. placement package for CSE students) and a decent infrastructure.

All 4 of them lack in

- internship opportunities

- have weak overall avg. semester results

- availability of great faculty

Still, if I had to choose then I'd choose between IILM and IIMT.

The decision, though, is yours to make. best of luck
