You know, I just pulled out the measuring tape after reading that the X-Plus Shin is only 10" high... I've got the Banpresto, which is 9" already, so I've essentially pre-ordered another Shin that's a different (some say inferior) sculpt - only 1" taller.
It's almost too tiny to call X-Plus.
X-Plus has two scales for Godzilla pieces, 10" and 12" tall, though they seem to keep mostly to the 12", which is wise, really sets them apart from NECA or Bandai scales.
Unfortunately, with the size of Shin Godzilla, companies seem to be going for scaled back size or cutting proportions shorter. Banpresto vinyls have been 10" in height ('54, 2000), but with Shin G they went down to a 9" figure and it's still big with the tail, where Sakai's original sculpt is about 10", so they definitely made a choice to reduce the size.
Bandai seems proportional on the MMS 6" vinyl but shortened the tail a bit on the 11" MKS figure.
NECA is a bit off in overall proportions and usually undersizes Godzilla tails, but still, their tail is shorter.
Unless you're getting X-Plus with the atomic breath feature, I don't think it's worth the additional cost if you've already got the Banpresto, superior accuracy, better pose in my opinion, paint's the best thing X-Plus has over Banpresto.
But with NECA it's not so much as a stylized take on the character as it is just basic failure to nail a sculpt. Nevis figures aren't bad for their price (to a degree) but saying they might have taken an artistic or stylistic approaches giving too much credit.
Agreed, NECA's figures come out with a style to them, and I like it, but given their commitment to film accuracy with everything, it's not an intended style, it's just a sculptor who has a style and doesn't seem capable of matching the film design 1:1 to the level of Sakai or even X-Plus or some of the vinyl companies out there, but, some are quite better than a lot of Bandai Creations work.
