I've been shooting with SIIIs for several years now, and have yet to have one give me any sort of problem. Yeah, I'd love to have the bucks to be able to mount anything I wanted on the rifles I've built myself over the past eight years, but that's just not the case, so I buy the best glass I can afford for each rig. Right now, I've got four 6-24x50 LRMOAs, one 6-24x50 LRMD, and one 6-24x50 LRD, plus a couple of the 8-32x56 LRDs on LR BR rigs. No regrets where optical quality, click accuracy/repeatability are concerned. And yeah, I've compared the 8-32x56 side-by-side to a NF BR 8-32x56 at dusk, and still feel the optical quality is about the same, with even a slight edge going to the SIII's color rendition.
On the negative side - the tactical knobs on the LRMOAs vary some on ease of turning - one scope's knobs move easily enough so that I've got to be very careful when removing or replacing that rifle in or out of the drag bag. The others are stiffer, and are no worry. I've also got a couple of Vortex 6-24x50 Viper PST SFP scopes, and would love to have their knobs, zero stop, and reticle on the SIIIs. The SIII glass will resolve 223 hits on steel at 600, even when shadows from trees west of my backstop fall across the targets, while the Vortex isn't quite up to that task. So if Vortex could bump the quality of the glass in their PSTs to at least equal that of the SIII, I'd be in the market for that one, probably even sell off a few of the SIIIs to get 'em.
Whatever - I keep buying powerball tickets each week. I'll have a couple of Premier Reticle Heritage scopes if I ever hit any kind of a jackpot. But for now, I'm just glad the market for good glass is good enough so that we've got some of the mid-range price choices that are available.
