I have bought 1 or more of each of the rugers mentioned.
All ok so far. The 44 SRH has taken some heavy punishment, still as good as new. Same with the gp100, to a slightly lesser extent.
(I've been stricken with magnumitis, I shoot 90% plus heavy handloads.)
I did, however, take the time to hand select all three from several of each model. Sadly, there was an appreicable amount of QC between them.
