You've already got good target scope in the S&B and a good hunting scope in the Zeiss
Comments on your list of important features:
1.repeatability of turrets - you can get repeatable turrets in a $200 Burris or a $4000 US Optics riflescope. While not all scopes have repeatable knobs most reputable brands do.
2.lens quality - You've got to go really cheap not to get good quality lenses. High magnification and looking though lots of atmosphere (long range shooting) gives crappy images. Going from decent qualtiy lenses to the best that exist makes very little difference. It's not the lens quality that separates good quallty designs from poor ones. It's coatings and properly designed internal baffles and lens stops. A good test of a scope is to look a a distant hillside with the sun outside of the field of view but with the scope facing generally toward the sun. Look for loss of contrast, flares and other artifacts of stray light. The human eye can deal with a large range of brightness but it's can't do anything to correct for loss of contrast or stray light.
Even resolution isn't very important for a rifle scope to allow accurate shooting.
3.reticle - yes, every rifle scope has one. the question is what you want the reticle to do for you to assist in determining your point of aim. A simple crosshair works fine if you use external sensors and target knobs. I'm like the Horus mil grid reticles which eliminate wtiddling target knobs, but they don't help in making environmental measurements. There's no "best" way determine trajectories in the field. In the end your're still left with estimating downrange cosswind bullet deflection. There's no available scope or portable instrument that does that for you.
4.field of view - A cheap pair of binoculars has a vastly better field of view than any rifle scope for a given magnification.and resolution. Searching for targets (game) using a rifle scope is just foolish. Field of view in a rifle scope is proportional to: (eyepiece_clear_diameter/(eye_relief * scope_magnification)). It has nothing to do with scope quality, tube diameter, or objective diameter and it not an indicator of how well it will help you shoot. You only need enough field of view in a rifle scope so that once you've identified a potential target you can put the target within the field of view of the scope as you bring the rifle to your shoulder. That's generally not a problem up to about 20x magnification for typical rifle scopes.
The function of a riflescope is to allow launching a bullet at an appropriate angle between the bore and the line of sight. That is not a fixed angle and varies with every shot. A good scope will make the process of detrminging that angle, setting the angle, and holding the line of sight on the target while firing as easy as possible. Bad scopes make one or more of those more difficult. If you want picture window views use binoculars or a spotting scope.
Also worth considering:
Price : Does the price keep you from buying better ammo, a better rifle, or spending money on trips to hunting grounds or target ranges? If not then expensive scopes are nice and maybe "better" than less expensive ones, otherwise they're a detriment.
Ruggedness. - Many $200 scopes will withstand the recoil of a 30-378 Wby with a brake or 50 BMG sporter. No scop I know of at any price mounted on a rifle will survive being droped four feet onto a rock and landing on the objective bell. Does you're warranty cover that? A broken scope puts an end to your day's activity for whatever reason it gets broken.
