I have three Leupolds, one 6.5-20x50, one EFR 6.5-20x50, and a mid '90s era 30mm Mk IV 10x. I also own one NF NXS 5.5-22x56 scope. IMHO, all are built quite well. The optics in the NXS scope are decidedly better, however, than those in any of my three Leupolds. Specifically, the image quality in the NXS is better at the edges of the field of view, and it's been my experience that maintaining an exact proper eye relief distance at high magnifications is less critical with the NF scope. Sorry that I can't speak directly to the VX line.
