I trained a lot of Air Force student pilots....best guess, about 400.
A significant portion were EU grads. (maybe 8%)
And not one of them performed better than brand-new guys with 20 hours of flight screening.
I think every one of them thought to himself on day-one: "They say it isn't going to help, but I'm going to kick (donkey) here."
And on graduation day, they would say "You were right, EU didn't teach me a thing to use here."
You can use that two ways:
1) EU is not helpful for a military career towards fighters or fighter-like flying.
2) It may not be all that advantageous for a civilian career. Good training, but you could do just as well for far less money elsewhere.
EU was a legitimate school during WWII. But now, I see them as part of the Military-Industrial complex. The fact that they have their tentacles so far into military Masters programs ("Pay your fee; get your B is the standard cliche), with questionable instructors for that program (recent EU Masters grads in my squadron were teaching classes they had attended just six months before!) for exorbitant fees gives me that conclusion.
