This is going to sound weird, but I would basically say the opposite in every case.I think Luepold glass is better for comparable models. VX3 is better than Vipers. VX5 or Mark 5 is better than razors IMO. All are good functioning scopes and I have never had issues with either brand but I like Luepold VX5 for my hunting rifles
there is a +/- adjust but lupolds are a pita to adjust vs a vortex that is simple turn out i fight that same issue on my 1.5-5 but its a me problem because it depends on which contacts i use...my colored contacts are 1 step stronger and field is clear but reticle goes out clear contacts same adjustment reticle gets wonky. i gave up its on a brush gun anywayI have a vortex crossfire2 4-12 on my deer rifle for pa and I really like it for all the more it cost. I've had 2 different leupolds and I just couldn't get it adjusted right for me. No matter what either the view or the reticle was clear but never both.
