Which B.Tech branch is better in terms of scope between CSE and IT?

Both are same but there are some differences between them. Computer Science and information technology syllabus is approximately same but in 8th semester, only one subject is changed in IT. Companies and recruiters first prefer CS students over IT students.

Both of them have a scope as they almost have same subjects. There is not much of a difference. But, you should take CS as it is a core branch. Good luck.
