GM first, Motive Second. Both will be quiet and last just as long as anything else, but the vast majority of GM/AAM gears hit the pattern right the first time if you take your time and measure, and that is important for the DIY people.

OEM, USGear or Precision. (Percision bought all of USGears machines a few years back when they re-tooled... its of the same quality) and then Motive... which is hard for me to say. A couple of years ago... Motive was ****... and we would use anything but them, but they changed a few things over the last couple of years for the better.

I wouldnt go as far as to say that....
The answer is related to metallurgy, but, it is not specifically because of material composition or manufacturing... Nor does it have anything to do with racing or what day of the week they were made... as it also has nothing to do with the design of the pressure angle in this specific application.
It has to do with the related material hardness. Richmonds have always Rockwelled at 62 or better (for the 8620 gear sets) while the rest of what is available from other manufacturers (for 8620 gear sets) is between 56-58. The difference in material hardness by it self... changes the specific materials resonant frequency. That combined with the typical set relate issues... I am not surprised that most have noise issues with Richmond. What I do know, is that they have a very small and hard to find sweet spot to set them up noise free.
I have set them up dead silent... and I have also had my fair share of SCREAMERS. It is the gamble you take when you select Richmonds...
The change in hardness has to do with combating tooth deflection, in high impact loading applications... like that of drag and off road racing. For the most part, in those applications, noise is the least of the worry and any increase in strength is welcome.
