Well, in such a case where you get blocked and don’t understand what to choose then you should discuss it with your parents and seniors in the particular field. They will help you to sort out which field you should choose and what benefits you will get by choosing that.
But as far as I know, there are always some things common like you do programming on microcontrollers and use Raspberry pi if you are in ECE. But there is a limit to coding in ECE.
If you see in CSE and IT both the fields are core coding branches. If you are passionate about computer science I would suggest IT is the field you should opt for. At the same time, NIT Allahabad is a good college and it does have its reputation.
So, this was all the data I can assist you with but my personal suggestion to you would be to take a long-term decision. Both ECE and Computer Science are good courses but you should identify which one you are passionate about and how are its prospects in the future. Only then you will be clear to choose the best for you.
