I don't think that Leupolds are bad optics at all. I do think though that at one time many years ago they were at the pinnacle of optical quality, and have now been surpassed by many manufacturers.
I've owned two Leupold MK 4s, which I would argue are better than any of their Vari-X lines. Optically they had nice glass (although glass clarity is VERY subjective). I would though, rate both of my Sightron SIIIs as having slightly better glass, and my US Optics has definitely having an edge in glass, although they aren't night and day apart.
Functionally, the Leupolds never gave me any issues. The Adjustments were on and repeatable, and I loved the TMR reticle that the scopes had (1/2 mil marks). I did not like that Leupold used a milradian based reticle though, while still keeping MOA adjustments (might have even been IPHY, but I can't remember). I finally gave up the Leupys in order to get a scope that gave me the same adjustments as the reticle read (i.e. mil/mil, MOA/MOA). I still own one scope with a mil reticle and MOA adjustments, it is a Sightron SIII 6-24.
My first entry into the "tacticool" scope market was a Burris XTR 3-12x50mm with mildot. For what it ran me, it was a good optic for the duration that I owned it. Never had any problems.
I've heard that Bushnell is coming out with a 3200 10x with mildot and mil adjustments for around $250. For a fixed power scope it might be worth me looking into.
