Zeiss conquest will win this hands down since you have to spend considerably more to eke out a little better resolution as well as physical weight.
I would use a 3-9x 40 for any hunting i do. The New Nikon Monarchs are maybe 20 dollars less then a Conquest just as heavy and the resolution is inferior. You also have more reticle options with the Conquest all the Monarch offers is 2. Bushnell Elite 4200 is verycomparable glass but the eye relief is 2/3" less in most cases . Some places are selling the 3-9x40 4200 for 250 range and that is quite a pickup unless you are using a heavy recoil rifle.
