Is it a good choice to prefer IIT Delhi textile over IIIT Delhi CSE, considering the fact that branch change is quite hard in IITD?

IIT Delhi has a much greater brand value as compared to IIIT Delhi. IIT D is superior in many aspects, one of which is campus life. 

I have many friends in IITD Textile. They bagged foreign internships in the IT sector during their second year.

The coursework for Textile is very manageable. You’ll get ample time to practice coding on your own. Don’t worry about branch change. Even for a career in CS/IT, self-practice will get you through. Also, opt for the open electives offered at IIT Delhi. You’ll ace CS/IT placement tests, and secure a good job.

Thus, I would recommend you choose IIT Delhi Textile over IIIT Delhi CSE.
