After becoming US non-resident, during the RNOR, Is remittance from US bank to remittance app to Indian bank better or wire transfer better ?

Which option is cheaper ?

Option A:

Fidelity to US Bank to Remittance apps (Ria, Xoom etc) to HDFC

Option B:

Wire transfer from fidelity to HDFC

If option A: I have no clarity on which bank is the best non-resident bank ? I got capital one, discover, charles schwab and chase but does anyone share their experience please.
Chase seem to be needing 1500$ minimum or 15$ fee.
