Hello Aspirant,
See, the EWS certificate is authentic and beneficial for availing benefits in fee structure of general category candidates having Annual family income less then 8 LPA.
The EWS certificate be central or state is different. Also, if you get admission into a NIT or IIT from your home state then you would require a state EWS certificate. Bit, if the IIT or NIT they you would get admission to belongs to other state and not your home state, then you would require the central EWS certificate.
So, depending upon the place or college that you could or will get admission into, you have to opt for your EWS certificate.
But, if your are confused and uncertain, then you can opt and make EWS certificate for both state as well as for central.
Hope that helps. Good luck
