I also own both programs. I use Clothes Converter 2.2 for most of my conversions, as long as the figures are supported in the "autoconvert" feature (That's for one-click, automatic conversions between figures). If it's not in autoconvert, then I turn to Wardrobe Wizard, rather than deal with the manual conversion process in CC.

So, in regards to the list of figures from the orginal poster, Autoconvert will work on conversions between V3, S3, D3 and M3 figures. It doesn't support M2 or Miki. It does support V3/S3 to Jessi conversions, but not vice versa.

I generally try to use CC over WW because: 1) Transferring morphs to the converted clothes takes a few clicks in CC. In WW, it's a much more tedious process that involves clicking on individual body parts and a lot of joint parameters. 2) I find the CC interface easy to use (that's just personal preference.)

WW is clearly superior than CC in its wide ranging figure support, and in PhilC's customer service.
