Kenny, so we're comparing:
●Athlon Helos 4-20x50 FFP
vs.
●Arken SH2 Gen. 2 6-24x50 FFP
Reticle thickness (main line): ●Helos: 0.05mil (0.17moa)
●Arken: 0.03mil (0.10moa)
A thinner reticle (Arken) means that the FFP reticle will appear "smaller" at the highest magnification.
This seems to be a pretty significant difference.
And when I look at other 6-24x scopes I have in my database, the Arken is
thinner than the average: 1x 0.10mil (0.34moa)
4x 0.05mil (0.18moa)
1x 0.045mil (0.15moa)
4x 0.04mil (0.13moa) (rounded)
3x 0.03mil (0.10moa) (rounded)
➔=Arken 1x 0.025mil (0.08moa)
2x 0.02mil (0.07moa)
Magnification range: ●Helos: 5-fold (
5 x 4 = 20)
●Arken: 4-fold (
4 x 6 = 24)
A larger range (5-fold) means that the FFP reticle will have to get "streched farther" than a scope with less range (4-fold) — e.g., thinner at the bottom end of the magnification, and thicker at the top end —
provided that the reticle lines are the same thickness (which is not the case with Helos vs. Arken).

The Arken has a
25ft minimum parallax! The Arken has a 34mm tube.
That allows a (for a 6-24x) very high maximum elevation adjustment of 110moa.
At 36.6oz it's rather on the heavy side.
Hope this helps in your scope shopping decision!
I'll attach my Scope Specs Table for scopes 6-24x and 5-30x (a few 4-20x are mixed in).
