I skipped some of the posts here towards the end of the 2nd pageful, but having recently upgraded from having Vortex DiamondBack and Vulture... to now having Zeiss Conquest 10 and 15... another HUGE advantage is beautiful Depth of Field!!
So for Depth of field.... um... kind of think about it like the slices of the image you see in an MRI series. When you have a nice and deep Depth of Field, it's like being able to see the most number of MRI slices all glommed together without having to do anywhere near as much fussing with the focus knob.
Like the Vultures? Comparatively speaking they had a very narrow Depth of Field to them... so.. it costs you more time to verify an area has nothing in it since you have to fish a lil bit in front of and behind the initial point of aim you pointed the binos at each time you move the head on your tripod. (EDIT: when the surface you're pointing at is more horizontal in nature, obviously a super-steep hillside this benefit might be less impactful)
Your eyes and brain are presented that much more image data at a whack, so your efficiency at detecting stuff within the FOV goes significantly up!
