I don't have any instability problems, with neither AMD or NVidia (I have a computer with each).
What kills those drivers is ongoing support. Since they aren't at the mainline kernel, they lose sync, and upgrading the kernels turns into a lottery where sometimes I have to uninstall the newest one, not a big deal, but anoying.
