I'll post a few comparison shots here. COR to the left, ASS to the right. Although this is not the Uploaders' Forum, I would like to hear if this is worth making an offer. As I see it, the COR encode suffers from a lot of the same problems as the ASS encode (combing, rainbows, macroblocking, jagged lines, jarred movement etc.), but it is a bit sharper and has more detail. One major point against COR is that it is slightly overcropped, showing less picture than the ASS encode.
EDIT: Images removed.
