I have WoW, S&M and DVE (accumulated over a few years). Not sure for most people's use there is that much difference between them from a pattern standpoint. The WoW disk has more tutorial content than S&M. If you are just doing a "cal" by eye, any of them will provide the basic patterns to set the user controls. If you intend to use a meter and software, that's a different story. In that case I would actually download the free AVSHD test disc image which has sequences of patterns for CalMAN, ChromaPure and HCFR.
