Shock wave: sure, Aside from Superman and Flash (both of whom could clear the area), the Vision probably just took out both the JLA and Avengers - or at least the ones that Superman and Flash couldn't get transported out of the way. A weapon that takes out your team isn't a very good weapon.
The thing is, Superman isn't infalible. He's been hit by things coming right at him alot. He wouldn't be focusing on The Vision during the entire fight, and would probably be distracted by everything else that was going on.
