C4D is the program I normally export Genesis figures into, Cinema 4D.

 

In my opinion FBX has become the more stable of the two open formats.

Studio has had FBX Export for a while but the FBX Import into DAZ Studio is a relatively recent feature and looks like its been very well implemented by DAZ.

Given the choice between Collada or FBX, I'd always go with FBX.

 

From my quick test reported in my earlier post, the rigging was successfully transfered with FBX.
