In my opinion, B.Tech CS from IIT Gandhinagar is a better choice. I am listing down the reasons why I would’ve chosen IIT Gandhinagar CS over NIT Trichy CS-
IIT Gandhinagar is the 11th most preferred IIT. It is expected to show more growth than NIT Trichy in the coming years because of its IIT tag and greater government funding.
Thus, I would suggest you go to IIT Gandhinagar for your CS.
