Which one is better: IIT Tirupati or IIT Bhilai?

Most of the newly constructed IITs suffer from the same problems compared to the old ones. They include lack of infrastructure, unchartered territory, etc. If you have to choose, go by branch and not by the IIT brand name. You can opt for other colleges like BITS Pilani, NIT Trichy/Warangal as they will provide much better opportunities, considering placements.

If you want to study CSE among these two top colleges, it won't require comparison. Both are doing well and have equally good placements, average packages, and campus life. So, for other branches, IIT Bhilai will be a good choice because practicals and research work are better at IIT Bhilai.
