Both are not the same and which one to choose depends on your interest. 

CSE- doing coding work;

ECE- dealing with low voltage work (chips,semiconductor devices);

CSE:

Coding is at a boom these days, rising no. of startups need developers and coders. Options are wide in computer science, lots of computer and assembly languages to be learned. But the thing is apart from being so much wide, CSE people often bound themselves in areas which they dont think they or are sure of in excelling! CSE all about!

ECE: Its a evergreen field.  It deals Electronics(Embedded systems, robotics, VLSI etc. to be named a few), Communication (Networks i.e. Networking) and Coding. You can “SWITCH”. This is the best thing. Switching is the only thing which can be possible in ECE. You can check more about ECE here: ECE

By check the scope for both in the above you can decide which one you are interested in.
