Hello Samir,
BITS hyderabad is a prestigious campus, if you are able to get CSE in BITS hyderabad then choose it, because it is better than the new IITs. If you don't get CSE in Hyderabad campus and got a seat in desired branch at any iits you mentioned, then choose the IIT, if CSE is the only branch you want. 

Hi Samir,

You should go for CSE at BITS Hyderabad if fee is not a concern, reason being :

• BPHC has its own permanent campus whereas campus of IITs which you've mentioned, do not even have their campus ready.
• Higher average placement.
• Better overall crowd.

If fee is a concern, then you should go for new IITs.

All the best
