Yes , because Naglers don't correct coma, but they do correct off-axis astigmatism . The edge of the field in the Vixen of the same focal length would be worse as it is probably not as well corrected. Only a Parracor or similar will correct the coma, which is by far the least dominant aberration compared to filed curvature and astigmatism.
