Actually the most supported version is P4, P5 support is slowly gaining ground, but still no official support from DAZ. The only reason to get P5 is for the material editor which has a learning curve but is much more powerful and also for the rendering engine which is of better quality. But a better rendering engine usually eats up more ram and cpu. I would go with ProPack, no more bum files, and no more rsr thumbnails.
