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 in 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!
