Both the streams are different from each other where ECE deals with designing circuits and different electronic components and devices, you need to have a good knowledge of physics to excel in this branch, on the other hand CSE deals with programming these circuits you need to use logic to do programming. You need to evaluate which subjects attracts you more. The placement scenario is some what similar for both. Also it depends upon your knowledge in the subject to get a good package.

Thank you.

Hope it helps
