Nah thats BS. HDchina is a great site. Wiki encodes are maybe a smidge behind HDbits encodes.Let's put it this way: For someone to truly determine which is the best, they'd need to be a member at all 4 places. Aside from that: Anyone who picks HD-T or HDC over HDB/CHDB is just not a member at either of latter, or has no idea what (picture) quality is.
CHDbits is great for full BD's. But not everyone wants those.
