Hello,

Both the institutes together are very different.  AIT has a good reputation as a technical institute. Studying at Army college will shape you in forms of discipline and punctuality.

Where as,NIT Jamshedpur is after all a NIT and we all know that a BTech degree with a tag of IIT or NIT will always make a difference and will have more value.

Placements are good at AIT too but by solely considering the placements you can't judge any college,it will provide you a decent degree with an army background from the affiliated university and you may even get a good placement where as NIT Jamshedpur will provide you a national level experience with all the scholars around India and the experience will be way too different from AIT Pune. But a degree from NIT will always hold a great value. So it's upto you,decide what kind of experience you really want and then go ahead.

I hope this helps
