There's six minutes between your posts.
I dunno - yeah, it has the facial proportions close to right. The Medi's emaciated and creepy, the SSC Dagobah looks too human and has a Leno chin, the SSC PT one looks mean gangsta and the HT, while probably the best overall, just feels too jowly and bulbous with small eyes.
For me as a customizer (or as a subtle fix done by the re-painter,) the "split" dealbreaker you mention is a 30 minute filler job. I'd rather have a minor depression on the top of the head to fix than a facial sculpt that looks noticeably off.
And I don't judge any of these heads based on pics - I've had all of these heads in hand.
