The Zeiss Conquest line is a very high quality scope.Even though it has Japanese glass instead of the German glass,it is one of the front runners of the upper priced lower tier scopes.
The Victory line is a far superior scope than the Conquest.The quality of the scope is in another dimmension.
Kind of like comparing a base Volkswagon to a top of the line BMW. But the price tag is in another dimmension also with the Victory line scopes.
Like JP stated,Sightron scopes are very high quality optics. I really like the Sightron SIII series scopes,and have 4 of their 6-24x50 scopes as well as a 4-16x42 SII scope.The SIII series will run right with the Conquest in any catagory,plus has a great deal more adjustment range for long range work.
Another brand that will impress you with optic clarity and brightness,and is also a well built scope is Weaver.The Super Slam line is their top scope and is a very good scope.The Classic Extreme line that was discontinued for the Super Slam line is also a very good scope.Both lines have some neat features,and will also run with the Conquest in any catagory.
I mounted a Super Slam on my 458 SOCOM,and have been very impressed with the quality of it,and I recently purchased two 6-24x50 Classic Extreme's from Natchez Shooters Supply for my varmint rigs,and have also been very pleased with them.For the price,they are too good to pass up-Closeout priced at $350.
