On that reasoning you are pretty much left between choosing Vortex or Leupold (I'd pick the latter everytime).
However, some scopes are just less likely to break from the outset. Warranty is all fine and good but I'd rather not need it.
Nightforce are excellent and reply to their customer contact immediately. I wouldn’t hesitate buying Nightforce and I would choose them over Vortex or Leupold.
I would rather not need it as well. But knowing it’s there is a reassuring.
Leupold are good.
