I know it comes down to personal preference but I tried several types of sight setups and found a red dot covers too much of the bullseye for my taste.(aimpoint comp M2 and vortex sparc). Wound up with a 1.5-4x Leupold Mark AR(less than $300) that lets me shoot with both eyes open up close on 1.5 and delivers the pinpoint accuracy further out at 4x. liked it so much I also picked up a 3-9x version when I caught it on sale for another flat top rifle. The red dots wound up riding eastern bloc modern sporting rifles and work great for pigs :)
Again just personal preference but getting 4+" groups from a rifle capable of holding MOA just didn't cut it for me.
Sorry if I'm off topic since I have no experience with the specific sights you asked about or how you intend to use it, but just wanted to share my experiences when trying to choose a sight.
