The OS reverts to the OSX driver after most updates because you can't update the nVidia driver before the update (well, not without hacking the nVidia installers). The nVidia "web" drivers are OS specific.You have to update the OS and then get the new nVidia driver, assuming there is a new driver, which there usually is.
I have never noticed a difference between the nVidia web drivers and the stock OS X driver, however I've never done any kind of testing and I run the nVidia drivers probably 95% of the time. I've also always run CUDA where I can, though that's about to stop since CUDA support is vanishing. CUDA is significantly less stable than OpenCL or Metal with Premiere in some iterations of driver. Many, if not most, of the graphics related failures I've seen were attributable to CUDA. It is (was) faster though, which is why I tolerated the crashes.
My one system currently running Sierra with a Radeon card using Metal has been solid. No complaints. Recent experience is all with Adobe though, not Avid or Radeon.
Cheers,
