You may not get the core branches in old IITs and but you can get a very good branch in any new IITs as well as IT - BHU and ISM Dhanbad .. wud like to suggest you that go ITBHU and ISM , electrical @IT BHU is a very good option. If you are expecting a good rank in AIEEE then try for NITs.. as new IITs don have enough exposure and proper administration or proper management system. The faculty also there are less and they have to suffer a lots of lodging problems as they are mentored by the older IITs. It will take some Time for new IITs to be established as old IITs , NITs and other good collages like BITs, pilani etc.
