Hello ,

Honestly it depends on you and on what basis are you comparing. Both the colleges are great. There are several factors like if you want to have that IIT tag obviously go for it . IITs are a bit better in facilities as they get more funds from the government than NITs. Nit is a bit far from the main city but if you like such environment then it is a great campus. Now, most importantly the branch you are interested in and what are you offered is what matters if you get IIT then go for it .

Good luck.
