I have owned most of them. Rugers including Super Blackhawks and Redhawks, Freedom Arms, Smith & Wesson including 29's, 629's, and one 329, BFR, and Colt. I don't really mess around with reduced power loads. If I want less power I'll grab a .357
The Ruger Super Blackhawk was beat on hard as it was my only handgun when I was shooting silhouettes back in the late 70's. 240 grain bullet with a max load of H110 or 2400 was its standard diet. It never wobbled or needed to be re timed. Never really shot any of the others "loose" as most were not shot that much
If I had to pick one to consider it the strongest and most accurate it would be the BFR.
