I ran the Sightron SIII 8-32x56 for a couple/few years, they are excellent, they are one of those scopes that is seldom if ever receiving a negative from an owner. They track true, what they have, works, they have $1500 glass. A lot of guys on the fclass line were using them and loving them as less expensive nightforce benchrests.
I used my 8-32's not only for fclass, but also for coyotes, shot several coyotes sub 30yds and moving, of course it isn't ideal, but having a 1-4 power isn't ideal if faced with a 600yd coyote either... Depending upon your skill sets/background, erring one direction vs another may better suit you, for me, 20 years of waterfowling helps give me breathing room in what I can make work up close, distance is where I needed the assist.
I owned a Burris black diamond that went back with mechanical issues, I have read enough issues with the Burris scopes that my pick would certainly be the Sightron.
