Hi Apurba, I would suggest you to follow what interests you the most. There is no "best" branch of Engineering. If you ignore your interest and go with the herd, your marks might drop as you will feel getting dragged. Instead, go for your interested branch. Do not worry about which branch is better. Learn it with depth and I assure you, you will get the best job offers by cracking even the most difficult interviews. If you ask me personally, I would pick Computer Science as it interests me the most and I loved the core subjects myself.
