greetings,
firstly it depends on your interest totally.
however if you are skeptical, compare the syllabus of the two and find out which one are you more comfortable with:
http://dtu.ac.in/Web/Academics/syllabus/schemes/Mechanical%20Engineering_Final.pdf
http://dtu.ac.in/Web/Academics/syllabus/schemes/Electrical%20Engineering%20(EE)_06.03.18.pdf
the placements are more or less the same. hope this helps.
good luck
