Which is the better institution to go to, IIT or NIT Trichy?

Before understanding the prospects of either institute, you should rather find out whether you want to go for an institute based on its tag name, or the branch you are more inclined towards. One of my cousins recently chose NIT over IIT because he preferred giving his branch more importance, than the brand name. 

• Yes, IIT is undeniably a superior choice to most other institutes. 
• But, if you do not secure the branch of your choice yet still opt for IIT, the decision might become damaging. 
• There have been several incidents with similar issues. 
• For my cousin, branches like Electrical Engineering, Civil Engineering, Computer Science Engineering, and Mechanical Engineering formed one group. 
• During this time, he decided to choose NIT Trichy for these first group branches rather than taking up branches from the second group, provided that the latter would not be greatly fruitful. 
• Subsequently, he interpreted similar actions while applying for NITs, BITS Pilani, and UPTU, while still filling the choices for AIEEE counseling. 
• Instead of having a borderline alternative, he kept his options broader. 

It is suggested that you do the same. Keep similar options and determine what among the handful works best for you.
