My simple answer is - for the "money" currently only $159 I think there is nothing better than Carrara  for an all round software that will utilise daz AND poser content and imports and exports a plethora of formats. It is not perfect and that is more Daz's fault through lack of interest in developing and marketing Carrara. Someone said it is little different to Carrara of ten years ago - not true of course - many things added since then. If you can live with the software as is there is a lot to learn about what it can do as any regular user will testify. Forget the negatives here and elsewhere and give it a try

"Many things added..." - like what, exactly?
