Hi Aspirant,
There is no such thing as CSE with specialization is better or IT is better. It all depends on your interest and dedication to the course.On Academics basis, Btech IT is a slightly cut down version of CSE since only a few subjects will differ every semester. But with specialization it may differ a lot.However, looking at the current trends of companies in placement,Companies looking for a certain role  really think degree with a particular specialization will be better but sometimes there are companies who may looking for a person with all around knowledge of Computer Science or Information Technology, then there might be a chance that they won't allow you to sit for placements.
I think both courses are valuable and easy to learn, providing better opportunities in market also,now a days, the requirement in CSE(with or without specialization) and IT is getting increase.

Hope this helps.
Good luck!!!!
