Well, I was an NROTC grad, though I have to say, I wasn't quite mature or self confident enough at the time to be a good officer. I had plenty of good colleagues who came through ROTC and knew some good ring knockers, but the Academy types did have rather large egos.
One of the best officers I ever served with was a commander who was a second generation officer. He was a no nonsense type, but with a sense of humor. He inspired respect in his men and took care of them, which is the mark of a great officer. He also wasn't above bending the rules, when necessary. A chief who served onboard ship with him told me about a particular captain's mast (nonjudicial punishment), with a very belligerant sailor. After repeated displays of insubordination and disrespect, the commander told everyone to leave his stateroom, except the sailor. The chief said her heard two loud "thumps," one when the commander's fist hit the sailor (he presumed) and the other when the sailor hit the deck. The commander told everyone to come back and "get this piece of (expletive deleted) out of my stateroom!" Knowing the man, I have no doubt it was true.
