I certainly agree that the Leupolds, at least the old Vari-X IIIs, are very reliable. In fact, I own a few, all with illuminated reticles.
I know that you did not expressly say that the Elite 4200s are not reliable - you just said that the Leupolds are reliable. I won't twist your words, and I am fair and reasonable. However, I will say that, in my opinion, as I have shot many VX-IIIs and Elite 4200s, that they are BOTH equally reliable. I have never had any problems with them. Specifically, both have held their zero very, very well, and both track very well as well.
As far as the "outstanding" glass issue is concerned, yes, you make a great point in that it is probably more practical to have outstanding glass in binos since you use them for many more hours.
However, even though you may use your scope for only 25 seconds to make a shot, if you have outstanding glass in your bino, but then can't see the animal properly with "less-than-outstanding" glass from your rifle scope, then what? Granted, if you shoot most of your game during bright, sunny, clear days, and shots are always withing 100 yards with no obstructions, sure, any glass may do. But what about rainy days, dark days, overcast days, animals in thick cover where you really can't distinguish the color of the trees and brush from the animal's hide? THAT's where good glass comes in. And Leupold's don't have rainguard, and that's important to have, at least in my experience.
Look, I own many scopes, Leupold Vari-X IIIs, Elite 4200s and 3200, Nikon Monarchs and Pre-Monarchs, Burris Black Diamonds, and Nightforce NXS. The best scope for the money is the Elite 4200. It's only drawbacks in my opinion are: they are usually a bit heavier and longer, and their eye relief is not as long as I would like. Other than that, they are rock solid performers with super optics.
Now, like I said, I don't know about the new glass on the new VXIIIs, but if they are as good as Leupold says they are, then that might justify their price, which is the highest of most scope manufacturers, exclusing Zeiss and Swarovski. Still, I don't understand why leupold can't put a Rainguard-type coating on their lenses.
