There can be no one branch that is best for everyone. Every student can have his or her own specific best branch according to their preferences and priorities. Your personal interest will determine that which branch is best for you. If you have an interest in programming then CSE/IT will be good for you, if you have an interest in robotics then you can take electronics, if you have an interest in cars and automobile then you can take mechanical and similarly for other branches. I hope that this solves your query.
