Both of them are godd in their own ways. But it depends on what you aspire to become in the future. Both have demand in the aspect of opportunities. If you are interested in Computer you can opt for CS. Here they teach you how to develop logics, programmes, codes and how to develop them. But if you are interested in Communication, TC, communication devices like Mobile, etc, hen ECE should be your option. What we see a software Engineer doing cannot be undermined or overlooked by what an EC Egineer does. Infact ECE is a broad field where you need to be specialised in a particular domain like VLSI or Embedded, etc to get jObs. Now a days even ECE Engineers learn subjects like DSA, OS, SQL, DBMS and then opt for opportunities in Software Industries. Instead of doing that , you can opt for CSE directly.
