I've got an Athlon Ares 4.5-30 x 56 and a Sightron S3.
The Sightron has great glass and seems to track well. But above 16x I find the eye box to be very very small.
It may be because its only a 50mm objetive and the exit pupil is smaller at a given magnification than the Athlon. But it shouldn't make that much difference having a roughly 10% larger objective.
The Athlon is much easier to shoot behind when you are in a less than ideal position with a comparatively forgiving eye box.
