As a guy who delivered one legacy aircraft to the NA Museum in one tour and took delivery of new aircraft from the factory in the next, I can say that both are great experiences. By that, I mean having the opportunity to enjoy the pluses and minuses of flying old and new aircraft in general. For instance, there is a great comaraderie among pilots/nfos/AWs/mechs in a legacy squadron for having "survived" the lean days of retiring an old bird. There's also a kind of cred by association with the old guard, even if you were only around long enough to graduate your CAT 1 syllabus, score a HAC/PIC designation, and retread. Minuses of such a tour include not enough money for toilet paper, and a general feeling of invisibility once the new aircraft and people start showing up. I think the benefits of taking delivery from the factory speaks for itself. But some of the drawbacks aren't so obvious. For instance, I was part of the T-6A cadre at Vance AFB and even the best of us ate crow for blown tires and tail scrapes. Thankfully, there was some tolerance for those kind of shenanigans for a short window of time. On the MH-60S side, I've noticed that even now (transition + 8 years), our maintainers come from literally every community in the navy and need lots of time to get comfortable with the Sierra's (and HSC's) quirks. Not sure why that's the case or if other communities experienced the same thing.
