I had 3 Athlon scopes to play with. The lowest end BTR FFP is the same as the $250 Primary Arms with a nicer reticle. The turrets are mush.. so much so I didn’t even test the tracking.
The Athlon Ares 4-27x50, has much more distortion and way to thick of a reticle when compared to the 5-25 Vortex Gen II PST, turret feel is also better on the Vortex in the same price range. The Night Force SHV F1 seems similar to the GenII PST, but I didn’t care for the thick Mil-R and extra $ over the PST puts it just outside your price range anyway. These scopes all were used because they could focus at 25yards or lower for a 22 trainer. The overall goal for the 22 is to have the working range of the parallax/focus for the matches ranges I’ll shoot, 22NRL starts often st 25 yards.
If 50 yard parallax is no big deal, then the XTRII and the turrets are nice, the glass maybe a bit better than the Bushnell ERS (not gen II).
I din’t have the sighthorn. The only ones I’ve seen have lots of magnification but are dark. That might be because I was in an S&B or older USO 35mm. I did not know.
You asked and all you asked - Which has the best glass, and tracks consistantly?
Glass really should not be your first priority- in the sub 2k market and might be one of the last questions I’d ask.
I am not saying these will not work, just that you should prioritize based on other things than the glass.
For instance, my 22 trainer, needed to 1st focus down to 25 yards, be FFP, have a reticle that I could work quickly behind, turrets needed to feel good and easily used (I could always map them). Internal elevation and FOV were not of a huge concern, but generally on the other rifles it will be on top of my list for either a long range system or a short range hunter.
My point is, maybe rethink what you really need before you worry about “the glass”.
What does one do with a Sighthorn that only has 4’-16’ FOV at 100? fine for paper but not much else.
You can have Hensold clear scope, but if you don’t have the elevation shoot your target does it matter?
