I still use most of the Generation 4 figures because I hate DSON.  However, I recently moved to the Genesis 2 figures because there was better clothing available especially for the male figures which are often neglected.  I got V6 for free just for buying a cheap prop item.  If I could convert Genesis clothing back to V4, I would do so because I could get rid of DSON. Even trying to convert clothing without PCF is a pain and often requires a lot of work or giving up.  Exporting from DAZ Studio doesn't always work.
