tlaero, your avatar looks just like the one you had previously. So I don't see Genesis there.
Yes, DS4 is free until 31'rst this month, so it's worth getting. You can't beat the price of 0 (zero).
The price for DS4 Advanced at the PC-price is at present $137.97, and $257.97 for DS4 Pro, and they won't go down as the PC-price is 'set' (I think). So anyone should at least download the free version of DS4 and try it. There's nothing to loose. I checked what the other versions have that lacks in the free version and here they are....
(Advanced and Pro):
-64-bit support in dynamic cloth
-64-bit hardware support
-Auto-fit
-Mutli-layered image editor
(Pro only)
-FBX Exporter
-GoZ Bridge to ZBrush
-3D Bridge for Photoshop
-Content Creator Tools with new Weight-Map Brush
-Transfer Utility
-Polygon Group Editor
-Updated Joint Editor
-Skeleton Setup
-Property Editors
-Texture Atlas
It all depends on what you think you need. I certainly believe that Advanced is woorth the price for the average user, while Pro is more geared towards content creators, or those who need the tools for unusual figures.
I got the FBX-exporter for DS3A a long time ago, and a lot of the other things are utilities that used to be plugins in DS3A (figure setup tools and so on), but probably made with greater utility and integrated into DS4A/P. I'll probably get DS4A if/when I can get it on sale, pushing the price below the current Platinum Club-price. Mainly for running it as a 64-bit program. On my workstation I have only 64-bit applications, and 32-bit on my laptop for showcase (not much used as I mainly work on the stationary).
