For me the Intel and ATi driver (or for that matter even the Matrox 
driver 10 years ago)
always worked superb (that is with latest greatest drivers there might 
have been some
compositing performance etc. regressions for one or the other). But at 
leas the available
of source allows to choose a suitable one, and fix issues as they appear.

The quality is influenced by many factors, for me the source 
availability is one of
the strongest ones - without it many other factors (such as security 
among others)
are hard to determine anyway. And on another side the NVidia driver 
rarely worked
at all. Mostly because of the sheer lack of x86 hardware on my side in 
the past,
and for the few AMDtel boxes other ABI incompatibility with latest X.org 
and OS kernel ont he other. For me this boils down to a near 0 usability.

If the CPU-land would be like the GPU-world, we would still not now how 
to enable
the i386 protected mode, nor how-to use vector instructions or other new 
when all programming material would be hidden by the manufacturers.

It's no wonder GPGPU is not in wider use today, when utilizing it means 
into a VESA BIOS sort-of-thing and no-one knows what's going on behind,
how to debug or if it works tomorrow or the next computer nearby.
