The difference, by ear
Both are melodic, keyboard-heavy and built for large rooms, and the two get confused at their commercial peak.
Both are sung cleanly and move at much the same pace, around 100 to 150 bpm. Songs run longer in neo-prog: usually 4 to 10 minutes, against 3½ to 5 minutes in Arena rock / AOR. To hear the difference, play Marillion next to Journey. They share a root in rock, and Arena rock / AOR came first, by five years.
