You have some really good choices. Most of my hunting scopes are Swarovski Z3/5 with the BRH reticle. I do have a Leica 2.5-10 with the IBS reticle. The Zeiss Rapid Z reticle is great, as well. I have no experience with S&B scopes other than shooting a buddy's at a few prairie dogs. The Leupold offering is good but again, I have no experience with it. Most of my experience is with the Swaro Z5 with the BRH and it is an excellent platform for hunting out to 500 yards, and more. I've used the reticle for steel target shooting out to 800 yards and it functions very well.
Good luck with your choice.
