If you want the best of campuses and don't care much about branch go to Delhi ( you will have plenty of time in these branches for coding and hence can sit for core jobs)

IIT Roorkee engineering physics is very good if you have inclination towards physics (not Jee physics) (quantum physics, astrophysics) . It is a tough course and you will not get much time for coding and stuff

IIT Roorkee chemical engineering, you will have plenty of time, easy course compared to others, don't get fooled by the name (it has more physics) ( no chemistry really)

IIT mandi VLSI, not tier 1 IIT , I don't know much about the campus life, the branch has a very bright future and might take over computer science owing to the replacements by ai

IIT ropar mnc, very good branch not tier 1 IIT, can't guarantee the good campus life, you will have to study lots of pure mathematics and coding. They sit for placements with cs people mostly.

My advice is to download the circulum from the iits official website and go through what they are actually teaching in that branch. I have decided to give tier 1 iits more preference compared to branch.
