Hello,

The best IIT college  i suggest from above mentioned is IIT bombay which has got a huge recognition in binding good and excellent academic knowledge to the students and provided with good carreer
Thank you

Hii Sahil..IIT Bombay, IIT Kanpur, IIT Delhi, IIT Kharagpur and IIT Madras are the best by far, in that order (basically all the old IITs). Amongst the newer ones, IIT Hyderabad is the best and no other new IIT comes close. Amongst universities that were recently converted to IITs, you can try IIT Roorkee and IT BHU also. And you need to also consider the environment which you need. 

Hope this helps you. All the best.
