I haven't had any major issues with the Poser DSON importer.  I've even been fortunate to either export props out of DAZ Studio as scenes (CR2) then import into Poser, or clothes that don't come with Poser Companion Files.  However, I find Ralf Sesseler's DSON Loader Python script does a much better job than DS.

Since these are the only options for Poser users to import Genesis models, I can't complain.  I don't really care about Victoria 7 anyway.  I just started using Genesis about a month ago and will grab everything I can until the G2 models run out of clothes because it seems they probably won't be supported much longer.
