I'm not sure anyone is going to be able to give you a complete list of advantages over V4WM.  While I respect the views of others in this forum 'bends better' is very subjective and it also depneds on what you render.  For instance I rarely do renders with nude characters so even V4WM has limited impact for me.  V4WM with the perfect series you use does help in most renders in some way even fully clothed so I use them a lot.

I stress I do not use Genesis myself but from comments form others I do see a great advantage if you decide to create aliens or other creatures.  Most of my reluctance to using Genesis is the fact that I know there will be a large finacial outlay to make it a worthwhile purchase, as with most other new figures, and I have yet to see what it can provide for my type of render that V4WM cannot.

That said, now that Genesis is in Poser there could well be something that I would regard as a 'must have'.  It would be a good idea to keep an eye on the other thread 'Poser heaven has arrived' as there are renders from Poser now being posted that might be of interest.

 

 

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.
