I own several of both scopes in both powers, 4 and 6...
The Weavers are good scopes.. with good features and attractive prices...
If I was setting up a rifle for a hard hunt in bad weather, I have to admit, I'd mount the Leupolds any day over the Weavers...
for optic clarity, I don't see any difference in any of the Weavers, as compared to the 4 or 6 power Tascos that I have...
and their optic clarity is every bit as much as I would ever need...
however on the straight power Leupolds, I still see the better clarity...
I think the straight power Nikon Buckmaster is closer to the Leupold in clarity, but it is definitely closer to the Weaver in price...
I wouldn't part with my Weavers, but I'd part with them before I'd part with my Leupold Fixed powers..
