Any character till the Victoria4 generation can be used in both softwares. It's just that in Poser, you may have to either redefine or to modernize the material settings, as often for these generations their vendors are more in a hurry to forget than to update their items.
When it comes to more recent Genesis generations, it may be difficult, as there was a way to transfer them (till Genesis3 easily) using the dson importer, which daz has definitively disabled.

When it comes to material management, for many Poser users, this is part of the fun, but not for all. indeed.
That being said, you may try Poser 13 during 21 days, even though you won't have the whole content.
Here on Rendo, you will find help, if you need.
