Yes, all of them are bad. Very bad. Some are better than others, but still not even close to the quality you get from DAZ.

I so, so wish I could tell you otherwise, but unless you want to give Genesis a try (No installation of Studio necessary. How did that rumour get even started, btw ?), I'd say sticking with V4 is your best option.

There are several JCM-fixes out there for her joint problems or you could use one of the weightmapped versions.

I sometimes play with the Poser meshes and just made a new custom face morph for P5 Judy.

You can do "nice" things with them with a little spit and polish.

But for serious work, there are simply too many problems that need fixing.

And even if you fixed all of them, you'll need to convert/modify/rebuild all the content you have.

Right here, right now there simply is no other practical solution than using V4 or Genesis if you need high quality figures for your work.
