Guneegoogoo bought my Nightforce, so curious to hear how he's liking my old scope?
If you are a Nightforce guy, I'd say buy the Competition and don't look back. Great reticle and glass.
If you have a budget at all, buy the Sightron, in a heartbeat, and will be totally happy.
If you like the feel of the best, buy the Schmidt, which to me has the best glass and serious "Swiss Clock" feel to it, but it comes at a premium cost, and has a couple little quirks.
Also keep in mind, I like to try new stuff all the time, am always buying and selling my gear and playing around with different things, so do not take that I sold the Sightrons/Nightforce scopes as a knock against them, not at all. Am going to be trying out the new Zeiss Victory V8 4.5-35 here in the next 7-10 days, and will see how it stacks up to these other scopes.
As always, just my personal opinion with hands on use, and definitely others will feel differently, and not saying anyone else is wrong, just my thoughts, and sharing my shooting buddies opinions.
