Re: Horus scopes
The "busyness" of the Horus reticle is a familiarity issue. People who have used one for long get used to the reticle, and it's not a problem.
I would not recommend the Horus scopes. They have a reputation for unreliability, and HorusVision has a reputation for being a pain in the ass to deal with. In my experience, both reputations are well-deserved.
I owned a Horus scope, briefly, before I returned it, and replaced it with a U.S.O. with a Horus reticle.
I sold the U.S.O./Horus after noticing that I can shoot targets out to 600 yards using only holdovers from a 100-yard zero with a conventional mildot scope having 5 mils of marks below the main crosshairs, and that's about as far as I care to shoot that way.
So, in short, my recommendation is that if you really want the reticle, get it in a U.S.O., Premier Reticles, or Nightforce scope. Avoid Horus scopes - and HorusVision.
