Hello There Aspirant!

NIT Trichy would be a better option here because NIT Trichy is rated as India's best NIT and is ranked 11 for Engineering colleges in India.

NIT trichy has

1. Good Faculty and good teaching
2. Good Infrastructure, except for some minute chanes
3. Lots of Research activities go on, so if you are good and a professor likes you, you might get to work on research

Also, there is more scope in CSE as a field, which would be better in the longer run.

Hope this helps

Dear applicant although both the branches opted by you, COE and CSE both are equally competent but considering the ongoing trends Computer Science Engineering stream would be a better choice and out of the college option chosen by you. Delhi Technological University is indeed a very good choice as per faculties, placements and all, however NIT Trichy is better considering future career prospects and assured CSE placements with package starting from 5-8 LPA.
