I have had good luck with the Leupolds I own. I do not use them much for longer range shooting, so I wouldn't say I have really tested their repeatability beyond doing occasional box tests.
That said, I would say that the features of their product lines are migrating away from what I value. Based on my hunting style, shooting habits, and how I have been conditioned over 20+ years of hard use of optics on my issued M4; for my needs I would rather K.I.S.S and not have exposed turrets. At this point every Leupold at the VX3 level or above have CDS. I would really like to get my hands on a 2.5-8 VX3, but at this point I need to try and find a used one as I don't want a CDS.
I know some don't like them, but I have fired countless rounds using a stadia type reticle, and for me this is far more useful for my type of hunting. Leupold seems to be reducing the availability of these.
So at the end of the day, I think all companies produce the occasional lemon, but what is making buying a leupold harder for me is their scopes just don't match my preferences....
