Have had all 3 at some point.
I still have 2 Midas Tac’s. My experience with them are on .22LR
Diamondback 6-24 was very milky above 18x-19x. Made it really difficult to use.
But it was the most affordable at the time. I do t recall any other real issues with tracking, zero or eye box.
Sample of one.
Arken was a 6-24 and the only example I had wouldn’t zero at 50 yards. Ran out of windage. Sent it back and sold the new one. The ones I’ve looked through had a very fine reticle. Difficult for me to use and strictly personal opinion. I don’t recall any issues with the eye box. Never really had a chance to test tracking or zero retention. Sample of one for me.
I know other people who have used them with great success.
I’ve had (4) Midas Tac’s. One 5-25 and 3 6-24. Still have the 5-25 and one 6-24.
Personally have had nothing but great success with these. Glass and dialing hve been great. Glass is the best of the 3 scopes you’ve mentioned (IMO).
There have been times where I’ve had to adjust zero from trip to trip.
Those time consisted of about a half MOA at 50 yards. So, yes it did move, but not a lot. Eye box is very forgiving. Turrets and zero stop are great and I liked the capped windage.
I’m not sure if your intended use but if the 3 you mentioned, I’m taking an Athlon every time. IMO.
