Everyday on this forum we all respond to the same question about which scope is better. Obviously we cant compare a nightforce to a vortex viper pst and so on and so forth. I think every scope is different to every person. I have a viper pst,mark 4 and a vx3 8.5/25 thats brand new. I was out shooting the other day and my dad and one of his friends stop by to run there mouths like usual. I told him i just got the vx3 and they wanted to look through it. As a comparison we all looked through every scope several times at a target at 600 yards with the highest magnification. The conclusion was quite interesting. Everyone here would assume the mark4 would be the winner. My dad picked the viper pst,his friend picked the mark 4 and i thought the vx3 and the mark 4 were almost the same. So i think its just up to you looking through every scope. I think the best scope to look through would be a schmidt and bender but then again its like comparing apples to oranges with my scopes.
