I did notice a small difference in aliasing - in fact in the sample you sent me, there was considerably less aliasing in the Seavus logo with w3 than there was with yadif. Not really noticeable with video in motion, but can definitely see it in the static logo. I didn't do a whole lot of other comparisons though. If the performance could somehow be optimized, it might actually bring some quality difference, but perhaps not enough until we have stronger CPUs.

I was able to play video OK on my i7 workhorse machine in XBMC with w3, but the i5 NUC just couldn't keep up.
