One of my cousins, being a part of the institute, mentions that NIT Agartala has been amongst the list of most underrated technical institutes all over India. Since it is unfavorably situated in the North East side, which is commonly not the best hub for technical industries.

• Dividing on the basis of every factor in hand, NIT Agartala is several steps ahead of NIT Mizoram.
• In fact, NIT Agartala has been recognized better than NIT Mizoram in all possible ways.
• Faculty, infrastructure, location, placements, college clubs and activities, work environment are better in NIT Agartala.

However, if you drop down to choosing between either of the former institutes, then going for NIT Agartala will unarguably be better than the latter.

Hope this helps answer your query, wish you all the best!
