For Cinema 4D I use the old OS9 free plugin and Kuroyme's InterposerPro, and both work really well. The OS9 plugin only allows you to host the Poser animated character and render it there. Interposer Pro actually brings the Poser content into C4D and allows you to open it, manipulate it, and compose characters and animations in C4D through the Interposer Pro interface, tho, the graph editor in Poser is still a lot better for creating the animations. What I generally do when I use IPP is I'll create an animation in Poser, save it as a Pose, then go into C4D, create or open a saved character (with all the clothing, props, etc) and apply the saved Pose animation to the character. The only thing that keeps me from using IPP exclusively instead of the OS9 plugin is that IPP doesn't honor "Point at" (but he's working on it) which I use all the time for closup characters to keep their eyes focused on an object, but I can use it for more distant characters, and they render very fast, so it's really great for groups of background characters.
