Honestly, the best flight training I experienced at ERAU was not in the cockpit. The courses on CRM, large aircraft flight technique and systems, and flight safety provided me far, far more education on flying than the flight instructors did. I think when it comes to in class education, ERAU can't be beat. In the air just depends entirely on how much effort you put into learning it, and who your instructors are (just like anywhere else).
Florida > North Dakota. No questions.
ERAU's biggest drawback was the cost.
And no, ERAU will not give you any advantage in the military (being a pilot or otherwise) than anywhere else. However, there are ALOT of Riddle grads on active duty, so you'll run into people everywhere.
