You should always prefer a course acording to your interest, passion and skill. 

Before choosing any course always keep in a mind that which type of career you want to make in future. Choose the branch in which you can enhance your skills and you don't get bore. 

There is a always good job opportunities for a right candidate who have desired skills and knowledge.

All these branches are core branches and offer good future scope. If we compare the branches then CSE is the most demanding branch among all it privides maximum job with good packages followed by ECE, Mechanical, Electrical, Civil and IT. 

You should focus on to get top colleges of engineering as you will get good placements and teaching in every branch. There is a lot of competition envolved to get good colleges so plan your studies accordingly.
