Go for Osmania University if you don't want in the NE states. Osmania University is all good in terms of many aspects and comparable to NITs of NE.
First of all, every college is good. Everything depends on the students and how he/she is. Thus as per the question, my answer will be if you choose NIT, then go for Agartala or Silchar, else choose OSMANIA University.

Both are same. However, in recent NIRF ranking Mizoram University has good rank than Burdwan University. However, Burdwan is an old university so peoples prefer. But, from my view Mizoram is better, as it is a central university plus JEE rank is high out here.

Go for B.Arch in MZU. It is good. The planning department is quite good. Department is new, but still got some good names. Moreover, you won't find many Universities with B.Arch. Only two central universities provide B.Arch here, and here NATA score is better.

As per the insights, JIIT is said to be better but in my opinion NIT is NIT be it in Mizoram or Delhi. Moreover, some factors do play a role but if u have enough talent u can succeed well. Afterlife is more important.

One NIT is in Sikkim and same for Mizoram. However, these NITs are quite low ranked due to various factors. Still, it's a prestigious college.
