As according the your question,I think CSE is better than IT.As IT is more of a Professional track course. You are taught about systems and their functioning on a need to know basis. You are taught regarding the basic applications of a technology. It makes you an expert at the surface level of the tech, which will aide you to develop skills required at the industrial level. A good example would be a Network Administrator. You need to know about Networking and some basic hardware and software rules. IT can teach you what you need to know about their functionalities.
Computer Science and Engineering on the other hand, is dedicated to both professional and research tracks. A Computer Engineer is someone who would have indepth knowledge about the Hardware systems as well as the Software systems. Although, Computer Engineers are often categorised with Electrical Engineers. As they are both dedicated to expertise in the Hardware division while having above average knowledge on Theoretical or Software division of Computers.
Good luck....!

Dear friend,
Both cse and it has equal opportunities and scope .Both branch have same cource for 3 years , there is a difference in course only in 4 year .
So never think about the best department,just focus on your interest.

Being a cse student ,according to me cse is better than any other branch in placement, package or job opportunities.

So if you are considering to choose among CS and IT,i will suggest you to go for CS.
