Not a Swaro, but when comparing a 3.5-10x40 VX3 (marvelous hunting scope IMO), with a 2-12x42 VX6 (marvelouser hunting scope) 1" vx 30mm (obviously), I can report the following:
VX6 advantages: more forgiving eye box across the zoom range, especially at highest mags, best of any scope maker anywhere at any price that I've personally seen. Better glass, better reticle, more W/E range, relatively lightweight for a 30mm tuber.
VX3 advantages: smaller package, W/E adjustments are "clickier".
