AMD is better at providing documentation needed to write open-source drivers, nVidia is better at providing a high-quality closed-source driver. From what I understand nVidia's closed-source driver is still the best for gaming and other intensive 3D applications followed by AMD's closed-source driver. The open-source drivers are not on the same performance level as the closed-source drivers, though the AMD open-source driver can be classified as "usable" (or better) in most contexts whereas the nVidia open-source driver has many issues since it depends far more on reverse-engineering the GPU's programming interface. Intel has the best open source driver of all of the desktop vendors (since the open source driver is their official driver) but its use for anything 3D is constrained by the relatively weak performance of their GPUs.
