I haven't noticed anyone saying that better deinterlacing was the only
advantage. I have seen posts saying that better deinterlacing was an
(additional) advantage. It's also the main thing that differentiates between
different GPUs (at least now that the drivers allow VC1 decoding on all
supported GPUs), since not all GPUs are capable of using all the
deinterlacing schemes.
