Remember that with 23 IITs and many more coming up, it’s not an IIT tag anymore. It’s IIT Roorkee, IIT Indore, IIT BHU, IIT Xyz tag.
Also, BITS Pilani, DTU, NSIT, IIIT H are in the same league as older IITs when it comes to tag and recognition in foreign universities because thousands of students from these colleges have made it to top universities abroad and have done exceedingly well.
In terms of infrastructure, college life, student quality, recognition, BITS Pilani beats IIT Roorkee hands down!
