I've tried both like DS or Poser and I prefer to render in Poser,in some renders Poser is faster and in some DS is faster If Poser is dying,in my view not,at least not in short or longer therm and if would,then I always will be using Poser like for posing etc and exporting to other SW like is 3DS MAX,its very easy to export from Poser to other SW I use most of my time FBX or other formats and no issues at moment,only thing what I would want is instancing and few other things

To OP,depends what you render and what are you looking,I still use mostly V4 and sometimes G3F,regarding G3,some their models I wouldn't touch,some do looks awesome and most of them use same maps which is same or similar like has been with V4,clothing some are just converted from V4 repertoire to G2 or G3,hair some looks good

Thanks,Jura
