Regarding direct comissions, prior service officers tend to be either some of the best or worst officers I meet, and rarely in-between. The difference often is those who wanted to become exceptional leaders and apply their NCO/enlisted experience and those who saw being an officer as an easier, higher paid life with no latrine detail. The other trend is that many seem to reach max potential as a CO CDR (where they excel), because they are unable to adapt to "big thinking" on staff. Subjective and shotgun blast opinions, and you don't have to look far for exceptions.
