Dear aspirant,

If you are sure and passionate about coding, you should go for IIIT-H. The coursework and coding culture in IIITH is amazing and it will open a  lot of doors for you in future. The atmosphere is highly competitive there but the performance of the campus in terms of coding and placement for CSE is way better. On the other hand, if you want to explore other fields of engineering you should go for NIT-T where you'll be exposed to various facets of engineering in the first year. IIIT-H is performs at par with IITs in the CSE department.

Hope this helps
