I would rate the Nikon reticle as the worst(by far) of the three reticles you listed. The Leupold reticle would be the best. I own all three and have shot a lot of ammo through them. I do not like the Nikon circles. The glass on all three is good. Some one suggested the Light Seeker. It is a good scope but I am 99% sure they are made by Burris. Or at least both are made at the same place.

The Leupold would have the best resale value. I think the Burris glass is the best of the three, but they are real close.

Leupold or Burris would probably have the easiest or best warranty repair center. I have heard of a few people having problem's with Nikon warranty work.

If you shop around you can still find some of last year's Monarch's on close out. They are a good scope for the money. I just do not like the BDC.

I just bought a new Bushnell 4200 Elite for a 223 varmint rifle I am putting together. I think this Elite isone step above all three scopes you listed, and at a slightly better price. Also before I would pay the Leupold price I would buy the 6.5X20 ZeissConquest. Tom.
