I was both ANG and AFRC. You are a bit more insulated from AD BS in the Guard, but only a little. I was in a mid-air in the ANG and thought, based on my later Reserve experience, better treated in the Guard. The ANG kept me out of going to an AD hospital, for instance.

That said, the Reserves might have better promotion opportunities for officers--moving for ARTs is a virtual requirement but making O-6 is easier, less political in AFRC. But, that depends on state AGs. In the ANG, you might, MIGHT be limited to your state.

More depends on your aspirations, the political climate and your ability, connections.
