This is sort of a philosophical question as I read it. My perception is some places treat you like any other FO where others might have a better comprehension of what you're good and bad at. Sure, we're all "equal" in the eyes of the FAA but we didn't do the same sort of flying.

Commutair and SkyWest both have RTPs that don't so much "transition" you as they do pay for your airplane time, then boom you're in as a FO. Some places really have the RTP factory going, like Envoy, Trans States, GoJet so my poorly educated [not an airline pilot] opinion is they probably have a better understanding of the unique helicopter pilot to airline stuff. If you go somewhere like Envoy, where they've trained 300 students at a specific flight school built to transition helicopter pilots to airlines, you'll find people all along the way that sorta understand your background.

Not saying Envoy/TSA/Skywest is any better or worse, that's just my perception having been researching this stuff ad nauseum.
