I think, the importance of different criteria and features depends very much on the type of shooting you want to do with the scope...!
My type of shooting: hunting (from 10 to 100 yards), and some informal target shooting, with a .22 bullpup (so,
springer rated is not a concern, but would be no. 1 on the criteria list of course). To adjust my POA I use turret dialing and/or reticle holdoffs.
My criteria, in order of importance (1) Price = around $350 to $500 (yes, that means that I'm not looking for super clear amazing glass....)
(2) Field of view (bottom end magnification) = at the very least 23ft @100y at the bottom end magnification (usually around 5x or 4x), for those close range stalking shots, better is 30ft (3x) and more
(3) Top end magnification = at least 16x, but better 20x or 24x
(4) Parallax = 10 yards min.
(5) Parallax adjustment = Side focus (not AO, it's awkward to reach so far forward)
(6) Turret "mechanism"(?) = turrets track true, e.g., a certain setting always moves the reticle to the same place
(7) Turrets = exposed (not capped!), because I often like to dial my elevation
(8) Reticle = Holdoff reticle (evenspaced hash lines; no BDC, no simple crosshairs); some numbers would be nice (every 2MIL/5MOA); grid style maybe; outside posts must be thick so that the reticle is visible on low magnification (as I require an FFP scope)
(9) Turrets and reticle speak the same language = MIL/MIL or MOA/MOA (so that I only need to memorize and carry
one range card for both elevation turret dialing and holdovers)
(10) Focal plane = Front focal plane (FFP; not SFP) (so that my holdovers with the reticle are always the same, no matter what magnification I happen to use)
(11) Glass quality = clarity, resolution, and contrast, yes please, because I'd like to see .22 pellet holes in paper at 100y with eyes that used to be young; however, I can live
quite well with chromatic aberrations and deteriorations at the outer edges of the scope image
(12) Illumination = Yes
(13) Max. elevation adjustment = At least 50MOA adjustment, to be able to dial for long ranges and heavy projectiles
(14) Zero stop = Yes (so I find my zero with confidence after being all over the elevation turret)
(15) Turret revolution counters = Yes (so I know how many revolutions my turret is turned up or down)
(16) Turret clicks per one full revolution = 10MIL (or 25MOA) (so I have to do less revolutions and get less lost between settings)
(17) Objective lens = 50mm minimum
(18) Weight = 30oz or more is just fine for me
(19) Length = 15" or more is just fine for me

PS: The Falcon S18i 3-18x50 FFP delivered (except for no. 14) ALL of the above. And often more! 90MOA elevation adjustment. Superwide FoV (39ft @ 100y). Springer rated. Under $400.
