You want to make our comparison between Mechanical, Electrical, and Aerospace in terms of Job opportunities,  Mechanical and Electrical are Evergreen Branches and their demand will not cease, Both Private sector and Public sector have a lot of vacancies for them, but competition is very high because of every other college offer this Branches. Aerospace is not very common but less demanding as far as India is concerned there are opportunities out there abroad. But In short first choice should be Electrical because It will remain demanding branch in Future.
