Careers in Electrical or Mechanical engineering are both intellectually stimulating and lucrative. It depends on your interest & capability.

To study, the mechanical engineering becomes bit easy as you can see everything working and know how things work. And i n electrical engineering it is hard to visualize the working as it is hard to see how a circuit or device actually work.

So I would suggest you to go through the subjects of both the branches and decide which branch has topics of your interest.

Good Luck!
