Thats a long list....where do they fall in your hierarchy of scopes?
My very limited experience is with a single SII 3-9x42. I bought one several years ago out of curiosity and was sorely disappointed. To my eye, it was not as sharp, nor as bright as a Redfield Revolution. Eye relief was worse and the eyebox was terrible causing a complete "blackout" with the slightest movement. To me, they are very low in the hierarchy of hunting scopes, but I read plenty of good things about them over and over on the internet so clearly they appeal to some folks.
Perhaps their appeal is with non hunting applications...
I have the exact same scope and have the opposite experience. Maybe eyes, maybe QC? Who knows. My eyes arent even the same day to day.
I like a nice eye box and find no issue with the SII 3-9. I admit mine lives on the low power of that range.
The SII are a heck of a lot better than the SI, which I didnt like. When the sightrons go on sale they are a terrific value IMO.
While its not a scope, my sightron 8x32 binos have been the best bang for the buck of nearly ANY product i have purchased in recent memory. Outstanding for the price.
