Yes edge deterioration as you have seen is very normal in wide FOV binos. As a generalization the better the optics and build qualities the less edge deterioration there will be. The Nikon 'Action' is also the entry Nikon porro version so it will be more noticable. The higher quality Nikon AE version displays less edge deterioration.
For many observers they prefer the wide panoramic view and live with the peripheral edge distortions as the central image is sharp.
