I don't think Xurge is doing stuff for Poser any more, though he's still selling the stuff he made before.  He hasn't even posted to Twitter in years.

At this point, it would be tough for any new figure to match V4 and M4 for versatility, just because they have such huge backlogs. Especially if you need less popular stuff, like ethnic characters, older characters, normal clothes, etc.

However...you might take a look at Dawn 2 when she appears. Some of the ethnic characters Cath has made for her look stunning.

Dawn 2 has been delayed by various events, including Cath getting covid, but hopefully she'll be available soon.
