which is better considering selected course

What are you asking?You have not specified anything clearly.I think you are asking that which is better branch or course for engineering.So,i would suggest that no branch of engineering is good or bad and you will have to choose as per your interest and skills.If you are just talking about placements only then yes CSE and IT has better placement opportunities in INDIA.But other core branches like civil,mechanical,electrical are also good in their perspective.Mechanical is said to be a core branch of engineering.So,you can join any branch as per your interest.The thing is that you will have to work hard and improve your skills so that company will lay interest on you.

Hope this helps.
