I like nikon for my LR. For Long range, leupold gets much more expensive. I like the Leupold M4 also for long range. but it runs 20% more for comparible Nikon.

I have a few target monarchs. Honestly if you have target turrets and AO, either works for me. You adjust out the parallax with both depending on your yardage.

Niether can adjust out mirage however. On a hot summer morning, it affects you targets real position relative to your eye too.
