I agree that at one point GPU h264 encoding was lower quality. But it's always been much faster, for me. And today's NVENC h264 encoding quality is approaching x264 levels of quality, until you get to the lower end of the bit rate spectrum. x264 really shines at bpp values of 0.05 and lower, a feat NVENV has yet to achieve.
