From my experiences CrossDresser3 has been the most reliable for me so far.
It usually works well, but I have sometimes had clothes (dresses) rip when posing figures.
There's a weld option which maybe I should have used to prevent this.
If you include high settings and transfer the morphs, it may take a while to convert, and you may think that it's hung, but it eventually finishes and does a very good job.
On HQ settings I think it took about 11 minutes to convert a quite complex outfit, RDNA SnowBride I think it was.
