I could see where it would be nicer to dial corrections while looking through the optic than trying to dial based on the elevation knob. It also means that say a throw lever, mount etc. obstructing your view of windage/elevation is no longer an issue.
Especially for those of us who are old and our far vision is still great, but near vision has gone to shit, because swapping to reading glasses to make elevation adjustments is horrible, and the magnifying elevation devices I've seen have all been fragile. I have no problem seeing a reticle but seeing numbers on some elevation dials is almost impossible.
I will say I think the weakness of the PS is that there's no direct connection to a range finder, for hunting. That's where something like the Eliminator 6 or Sig BDX has an advantage. The advantage to the PS, is you can still dial it like a regular scope, and use the reticle for holdovers. You can't do that with the Eliminator 6 or Sig Sierra 6 BDX because their reticles are not marked, you can do it with the Sig Easy 6 BDX, but it's still SFP so your reticle is only accurate at one magnification.
The Eliminator 6 seems more geared to hunting and more similar to the Sig Line (minus the rangefinder). I've ran a couple of the Sig's on hunting rifles and they are okay, glass quality is abysmal for the price point, you give up a ton of optical quality for the electronics in it. Its optical quality is about the same as a $300 optic, but it's handy to range a target and just have the optic illuminate a solution. The other issue with the Sig is the reticle is very thick because it has to work with the illumination points. Can't say for an eliminator 6 but I'd assume it's similar. Meanwhile the PS has a normal reticle because it's not having to illuminate dozens of points on it.
