Vineet, 

In my view IIIT LUCKNOW IT is better than any course Of IIITDM KANCHEEPUR reason is IIIT LUCKNOW is new IIIT and follows the sme curriculum as IIIT HYDERABAD which makes students more knowledge and industry orientated.

The next thing is placement. Placement stats of IIIT lucknow is far better than IIITDM kancheepur. 

Avg package of IIITDM KANCHEEPUR is 5.5 lacs where as IIIT Lucknow is 11.37 lacs. 

Highest for IIIT LUCKNOW 28 LACS FOR IIITDM 10 LACS. 

the rest depends on you.
