Which is better among E&C,CSE and ISE?

Branch you decide is based upon your passion and dream.my suggestion is if you interested in computer then you pick up CSE

Hey,
It depends on your interest completely.
If u like codeing and have good at analytical skills., then cs would be a better option.
Ece is more of theory. And there are new areas coming up like robotics which are growing fields in the industry.
IS is less of codeing, they would not go too deep into codeing part, but would have new and different topics to learn.
Students mostly choose cs as there first preference, IS as their second and ec as their third.
But finally it all comes down to your area of interest.
All the best !!.

cSE is better amongst all

It depends on you in which u are interested
But in India thereare more it companies
So there is more scope for cse nowadays

We can't say that which branch is very important. Every branch has its own importance. You should chose the branch of your interest.
