No target shooting here, but I compared the AV to the Conquest when looking for a 3-9, and I preferred the Conquest, even without the $500 advantage.
Then again, I also preferred the Zeiss 8x42 FL's to the comperable Swarovski model, so it might be that I'm just not a Swaro kind of guy. Maybe my eyes prefer a different kind of coatings - dunno.
With both brands having sterling reputations, go take your eyes for a stroll at the gun store, & pick the one that your eyes like best. Some may make fun of your choice, but I promise that I won't!
If only Jack O'Connor had written about the .270's effectiveness on Zombies, he might be known today as a decent gun scribe, and that cartridge might enjoy more widespread use...
