It actually depends, how you like your future to bell.

Choosing CSE will lead you towards software companies which will definitely provide you a better pay package than a core ECE company will provide to an average student.

To be precise, you may get a private job with a high salary structure. On the other hand, ECE, being a core branch, there is a good scope for government jobs too. For example, you can appear for competitive examination such as IES with ECE as your subject and the best part is you can still apply for software jobs if you are confident with your coding. But honestly telling, you will have to be exceptionally good at coding to compete with a CSE guy as far as PACKAGE is concerned. So according to me,

• If you are seeking for a high package- Go for CSE.
• If you want a broader range of opportunities- Go for ECE.
