It depends in part on what version of Poser you are using and the type of renders you are looking to create.  If you are using the latest versions that support weight mapping then there are a couple of versions of V4 that have been weight mapped and then there is Dawn from Hivewire along with posers own weight mapped figures.  On the other hand, if your figures are essentially clothed most of the time, then weight mapping has less of an impact.

 If you have Poser 2014 then the fitting room allows you to use clothes made for one figure on a different figure so a lot of that V4 stuff could be used on another figure.

 Best plan is to try as many figures as possible and find the one/s that work best for you. 

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
