Both are good companies with good contracts & good movement (today). A year ago, not so much for PDT. 6 months from now, who knows? Pay may be a little better at EDV, but not enough to warrant choosing them for pay alone.
EDV offers 100% DH & CXL pay, premium pay is 150-200% (mostly 150%).
I put zero faith in both the flow and the DGI. You'd move up much quicker with an OTS interview, no matter for whom you work. Thousands of pilots will move up to the legacy airlines in the next few years, without either program, IMHO.
