Comparisons with SSIM, PSNR and VMAF have already been posted in doom9, but one has definitely to make his own tests and optimize encoder settings, like constant quality versus constant quantizer etc. for ffmpeg NVEnc or rigaya's NVEncC.
One 'problem' I see with HW encoding is that BD-RB would have to analyze the user's HW in order to suggest the appropriate encoder settings.

I can't repeat it enough: the main reason for HW encoding is speed ... Usually my 4K encodes with medium to high settings run at 1-2 fps ... HW does the same with over 60 fps
