Hello Aatif, 

IIIT Hyderabad is much more better than DTU.

1. The quality of research and professors in IIIT H is far more superior than the other college you have mentioned.
2. Placement statistics of IIIT H is comparable to CS placements of the old 5 IITs . Be it programming contests, Google Summer of Code, jobs at Facebook, Google,Uber, Tower research , Microsoft- Name any of the IT giants of the world or any coding contest, IIIT H students are right there competing against the best of the best.
3. The only reason for not joining IIIT H would be that you absolutely hate coding !

Thank you
