Hello, if you have interest in a branch and are comfortable to work on this field then it's choice of interest.

As all Nit are top colleges and highly ranked. All are good choices.
But I would recommend you to go with Nit Trichy Metallurgy and materials science branch because Nit Trichy is ranked first among all Nit of India and placement wise, infrastructure wise this is a very good option.

Placements in all three branches are not like in Cs/It branch but if you work hard you will get a good placement.
