They are about the same in my opinion. I was in the same spot as you a couple of weeks ago. I bought the Leupold VX II 3 x 9 x 50 and couldn't be happier. The Nikon Monarch was a little more expensive, and they both pulled in light about the same. They both pull in light great, they both have a lifetime warranty, so really it's a toss up. I hate to admit this, but part of the reason I bought the Loopy was it looked better on my rifle! Good luck!
