Never owned a vortex, but have purchased 3 as christmas gifts. All doing well.
I an not a fancy gun person at all, but want reliable stuff. Burris fullfield II has treated me well 5 or 6 times already. They got 3-9 and 4-12. 400 yards I'd go 4-12. I practice to 300, but quit at 250, and often practice at 230 with a 4 inch gong. My 308 savage axis whacks it pretty often from a wobbly old picnic tabe at camp. Deer in open fields it's just fine in low light. NY recently changed from dusk to 30 minutes after, sometimes can be a bit rough in the woods past 15-20 minutes after dusk. I turn them down to low power and they're OK. They have the red ruby coating, which was great 20-30 years ago, but there's better stuff out there now. I'd pass on them if squeeking out a coyote hunt other than a good moonlight.
Never touched zero on any of them unless I am changing the zero or bullet load. Probably over 1000 rounds through a marlin 336. Couple hundred easily on each muzzleloader. Got one on my main 22lr. Even dropped that gun once or twice. 308 is kinda new, but doing well.
I am pretty much done buying rifles unless NY laws open back up with AR's n such. I may scope a nice CZ 22's, 48 year old eyes suck. I remember beating the old men at the blackpowder shoot a decade ago. Playing field is getting level now.........
